Math is a man-made thing. We, humans, came up with number systems and basic operations as well as complex formulas. Why? To explain the world. To say that, if you have $2 and I give you $3, then you now have $5. To describe the motion of a projectile. If an alternate world with intelligent species existed, they might have come up with a different way of expressing the world altogether. But to make sure that WE all get the same answer when solving problems, we use THE ORDER OF OPERATIONS.
@PattyObrien616 actually MrSirBurpsAlot is right. For an explanation why check flowiepanda's post, it explains quite nicely what the solution of the problem is.
@Lurmy101 That is one way of solving it. (48)\(2(9+3)) is also a possibillity, then you get 48\24=2 It isn't made clear what 48 is divided by, The notation is confusing, which creates two ways of solving it.
48 divided by 2 times (9+3)? are you kidding me? easiest problem. parenthesis first, so 48 divided by 2 times 12 is the new problem. doing 2 times 12 and that divided by 48, thats basically the problem backwards. so you do 48 divided by 2= 24. 24 times 12= 288. problem solved.
@PattyObrien616 first of all 48 isn't divisible by 18 so the answer is wrong altogether, and you forgot order of operations.you don't do 48 divided by (18+6) you do (48 divided by 18)+6.
order of operations:
1. parenthesis.
2. exponents
3. multiplication and division
4. + and -.
you are wrong! and either way weather the order of operations up there is wrong, there should be no 6 or 18 in the problem. anywhere. so... who's retarded now?
@MrSirBurpsAlot actually your wrong. let's get technical. 48/2(9+3) lets use PEMDAS-Parenthesis first so 48/2(12). Then you have EMDAS-no exponents so MDAS- OH MULTIPLICATION! 48/24. DAS-so division next which gives you TWO. retard.
@PattyObrien616 Actually, multiplication and division are done on the same step, whichever comes from left to right, as does addition and subtraction. That's the confusing thing about PEMDAS, it puts multiplication before division and addition before subtraction. It should be something like PE(M/D)(A/S).
@PattyObrien616 Actually, multiplication has the same priority as division and so do addition and subtraction. in which case you would do what comes from left to right. in the case of 48/2(12), 48/2 should be solved first and the quotient multiplied by 12.
@littledetail She may be stretching the truth, but something like that is still quite plausible. I am pretty good at manipulating variables and can solve advanced calculus problems with a minimal number of marks on the page, but I can't remember anything higher than 7*7 other than powers of 2 (though that's mostly due to rote memorization of binary numbers) and perfect squares.
@littledetail Not sure. But I'm an honors sophomore and I take Calculus and am able to comprehend concepts like limits, derivatives, and integrals, yet i still can't tell you, on the spot, what 6 x 8 is. it'll probably take me about 5 seconds to do 5 x 8, which i know is 40 and add 8 to it, which is 48. i never memorized the multiplication table in its entirety.
u dont explain why this works... the main problem I have with math is you are just expected to accept that things are the way they are... why does drawing the number of lines and crossing them work?
do one on mental arithmetic will you? a way to visualise in your head in every day life (supermarkets etc) that make it simple without a calculator *sigh* my maths teachers sucked so much in school..
The problem is not ambiguous precisely because we have the order of operations, which shows that operations are done left-to-right The problem could reasonably be considered ambiguous otherwise, but not as it is right now. :3
@Figolett You calculated that wrong. Multiplication doesn't come before division, you're supposed to solve from left to right. Just think about it... dividing is like multiplying by the inverse.
@flowiepanda You said yourself, parentheses first. Even though parentheses are "considered" multiplication anything that affects a parenthesis takes priority. If it was the multiplication sign x, it would be how you would do it. GETTING RID OF ALL PARENTHESES IS THE FIRST PRIORITY. So you would have to multiply by the 12 to get 48/24= 2. Or you could expand the parentheses first so get 48/(18+6).
@tombraidermasterman Anything inside the parentheses is first priority. 48/2(12) After that, you move on from P to M/D (since there are no exponents). 48/2(12) is the same as 48/2*12. Since division is seen first when going from left to right, we carry out with that operation: 24*12 = 288. If we apply YOUR logic to a problem like this: 3(4)^2 Then that would mean we would have to solve 3*4 and then square the entire value, (which we know is absolutely incorrect). I hope I've cleared things up.
@flowiepanda I said that getting rid of the parentheses was the first priority. If you get rid of them, the equation becomes more clearer. Getting rid of the parentheses DOES NOT necessarily mean multiplication. In the case of 3(4)^2 , you would get rid of the parentheses by solving 4^2 first, since in PEMDAS, exponents take priority over multiplication. Then it becomes 3x16=48. I hope you understand where I'm coming from.
@flowiepanda This is an illustration of the difference between how most people see math, and how true geniuses see math. Normal people see math as a rigid set of rules that must be followed to generate the proper outcome. Geniuses see math a a beautiful living process that can be modified or executed in a number of interconnected ways to generate that same proper outcome. You see a math problem on a page, she sees symbols on a page that poorly describe a beautiful living process.
@wormspeaker Are you implying that I'm not intelligent because I use examples and facts to justify my answers? Just because I use hard logic doesn't mean I don't enjoy math as much as anyone here.
@wormspeaker If you knew me personally, "normal" would not be a word you'd be eager to use to describe me. I'm not a genius, but I'd like to think I'm at least a little above average.
@flowiepanda I'll take your word for it. Though when it comes to things like math, there is a world of difference between "above average" or even "exceptional" and true genius. That is not to say that I am a genius when it comes to math, but I catch glimpses of it here and there. Math is what the universe is made of. It is what ties all of the sciences together. (Or at least anything that can be described with math is a true science.) Our ability to describe and understand it is what is lacking.
@AlexLloydPowell I disagree. (Not with the answer, that's correct). There should be no ambiguity when following the order of operations. And if there is, you can always rewrite it.
@MrFueler WRONG. PEMDAS Do what is in the parenthesis first, then complete the simple function from left to right hence 48/2 = 24 then do the other operation 24*12 which gives a net result of 288. This is how the Math Society does this problem. You do not distribute first, but do the P in Pemdas first. Then complete the function just like how we read
2:16 ?? I think that this is a very clever inside joke on your part, for only the most creative and perceptive to solve. The coefficient of 2 perplexes at first, then one wonders whether it might perhaps be a hidden message, leading one (in the absence of other guidance aside from the previous digits on the page, whose significance which I won't get into at this time) to seek answers in the Bible; since the topic is Math, of course we check the book of Matthew, with the chapter and ... (cont.)
(cont.) ... verse matching the time 2:16, and there we find this -- "When Herod realized that he had been outwitted by the Magi, he was furious, and he gave orders to kill all the boys in Bethlehem and its vicinity who were two years old and under, in accordance with the time he had learned from the Magi." -- which completes the circular reference by suggesting the elimination of the coefficient 2, and so the entire digression proves self-annihilating -- and exhilarating. Tanky fo de fun!! ;D!!
haha you hit on 2 of my pet peeves, the sloppy notation "trick", and the numbingly stupid method for multiplying binomials.
Every time my teacher made us repeat the steps to the "FOIL" method I wanted so badly to stand up and kick him in the balls. JUST FUCKING DISTRIBUTE IT MR HUDAK! YOU FUCKING SON OF A BITCH! AAAAHHHH!
What happens when there's a third or a fourth set of parenthesis thrown into the mix? where is your god now????
i learned multiplication/ division which ever comes first going left to right. that's means you would divide first then multiply after the parentheses using the P.E.M/D.A/S problem
It goes Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). For 48/2(9+3), Parenthesis first= 48/2(12). No exponents now mult. and div. From left to right we do 48/2= 24 and then 24 times 12 = 288
@pppfan103 No parantheses, exponents nothing. A simple math trick! Check it out! "Speed maths- Multiplying without multiplying". Click on my username and check the vid. Cheers.
@FlargTheKitty neither, the point is that you've been taught one correct way that may or may not be simpler than another correct way but regardless, they are still both correct
Hehe, I'll throw something out... you're assuming that the equation can only have one solution. Which is obviously wrong, as it can be solved two ways.
I dont see why 48/2(9+3) is badly phrased... Work inside parentheses first, 48/9(12), get rid of the annoying parentheses, 48/9*12, relationship of mult and division, 48 * (1/9) * 12, solve. -didnt look at comments- someone should totally explain to me my misunderstanding <3
You're right about solving inside the parenthesis first. The problem lies with whether the problem is interpreted as (48 * 12)/9 or 48/(9*12). There isn't any rule governing whether dividing first or multiplying first gets priority. Alternatively, 48*12+3 will always be solved as (48*12)+3, because mult/div gets priority over add/sub. This is just a math problem in improper form and has a technically non-real solution.
Y dont u just use the regular method dumbass? lets say u had exactly a minute to figure ur problem out... y waste 3 minutes when u could just figure it out faster than that.. this is a waste of time, ur method sucks, srry :(
@cvice30 The point of the video wasn't give a better method of doing multiplication; it was to give a visual representation of what is happening when you're doing "regular" multiplication. There's more to math than coming up with effective ways of doing things...
hey vi! (or anyone else that would care to answer) im in tenth grade and am starting honors pre calc (even though my genius school system decided to force me to take alg 2 before geometry) and am having some trouble remembering what to do when rationalizing the denominators of fractions when they contain i (ie 6/i or 6/6-i)....could you remind me since google cant?
As I see it 48/2(9+3) is not a difficult problem. Order of Operations dictates that you do the parenthesis, the multiplication and division next. Because the the division (48/2) comes before the multiplication [2(9+3)], the solution would have to be (48/2)*(9+3). My reasoning is that because multiplication and division are equals within OoO, the one that come first in the equation is the one that is solved first. The answer would come out to be 288.
Did anyone else learn the "lattice method" of multiplication? They taught us two methods of multiplication in elementary school, and to this day, I can't do the regular thing, I always have to use the lattice method. It involves drawing boxes and diagonal lines and stuff... My mom is convinced that it is a much more inefficient way to multiply, but it seems to work for me.

I don't understand why, but I personally love math. My sister however struggles with the basics and I'm hoping this may help her out :)
Thanks a ton

Isn't it obvious? Its 288. I agree, it's notated horrifically

@AlexLloydPowell I disagree. (Not with the answer, that's correct). There should be no ambiguity when following the order of operations. And if there is, you can always rewrite it.

@MrFueler WRONG. PEMDAS Do what is in the parenthesis first, then complete the simple function from left to right hence 48/2 = 24 then do the other operation 24*12 which gives a net result of 288. This is how the Math Society does this problem. You do not distribute first, but do the P in Pemdas first. Then complete the function just like how we read

2:16 ?? I think that this is a very clever inside joke on your part, for only the most creative and perceptive to solve. The coefficient of 2 perplexes at first, then one wonders whether it might perhaps be a hidden message, leading one (in the absence of other guidance aside from the previous digits on the page, whose significance which I won't get into at this time) to seek answers in the Bible; since the topic is Math, of course we check the book of Matthew, with the chapter and ...

(cont.) ... verse matching the time 2:16, and there we find this -- "When Herod realized that he had been outwitted by the Magi, he was furious, and he gave orders to kill all the boys in Bethlehem and its vicinity who were two years old and under, in accordance with the time he had learned from the Magi." -- which completes the circular reference by suggesting the elimination of the coefficient 2, and so the entire digression proves self-annihilating -- and exhilarating. Tanky fo de fun!! ;D!!

haha you hit on 2 of my pet peeves, the sloppy notation "trick", and the numbingly stupid method for multiplying binomials.
Every time my teacher made us repeat the steps to the "FOIL" method I wanted so badly to stand up and kick him in the balls. JUST FUCKING DISTRIBUTE IT MR HUDAK! YOU FUCKING SON OF A BITCH! AAAAHHHH!
What happens when there's a third or a fourth set of parenthesis thrown into the mix? where is your god now????

i learned multiplication/ division which ever comes first going left to right. that's means you would divide first then multiply after the parentheses using the P.E.M/D.A/S problem

braceletwiz98 4 months ago
It goes Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). For 48/2(9+3), Parenthesis first= 48/2(12). No exponents now mult. and div. From left to right we do 48/2= 24 and then 24 times 12 = 288

I dont see why 48/2(9+3) is badly phrased... Work inside parentheses first, 48/9(12), get rid of the annoying parentheses, 48/9*12, relationship of mult and division, 48 * (1/9) * 12, solve. -didnt look at comments- someone should totally explain to me my misunderstanding <3
TehMathWiztard 5 months ago
@TehMathWiztard
You're right about solving inside the parenthesis first. The problem lies with whether the problem is interpreted as (48 * 12)/9 or 48/(9*12). There isn't any rule governing whether dividing first or multiplying first gets priority. Alternatively, 48*12+3 will always be solved as (48*12)+3, because mult/div gets priority over add/sub. This is just a math problem in improper form and has a technically non-real solution.

As I see it 48/2(9+3) is not a difficult problem. Order of Operations dictates that you do the parenthesis, the multiplication and division next. Because the the division (48/2) comes before the multiplication [2(9+3)], the solution would have to be (48/2)*(9+3). My reasoning is that because multiplication and division are equals within OoO, the one that come first in the equation is the one that is solved first. The answer would come out to be 288.

Did anyone else learn the "lattice method" of multiplication? They taught us two methods of multiplication in elementary school, and to this day, I can't do the regular thing, I always have to use the lattice method. It involves drawing boxes and diagonal lines and stuff... My mom is convinced that it is a much more inefficient way to multiply, but it seems to work for me.
