EASY Solutions to HARD SAT Math Problems with ClockWorkMath.com

We have a comprehensive SAT Math Prep Course on a 5-disk DVD series for sale on our website at: www.ClockWorkMath.com ~ cost is $59. Here is the problem for this sample: "When x is a positive integer, if y = 3 - 5x when 2z = 10x + 2, what is the sum of y and z?"

Disclaimer #1 If you are the typical Math genius surfing the internet for bonus points on the SAT, you are probably not going to enjoy my solution to this style of problem. Why? Well, because my solution to this problem type is unorthodox. Furthermore, I do not follow contemporary algebriac precepts, preferring to go back to the 'original intent' of Algebra (see "The Comprehensive Book of Calculation by Balance and Opposition" by Musaal-Khwarizmi ~ 825 A.D.). As such, my techniques work for all students ~ even those students who are not all that good in math, and these techniques allow every student to crank out tremendous scores on the Math Section of the SAT using simple 4th grade math applications.

Disclaimer #2: "SAT" is a registered trademark of the College Board, and they were not consulted in the production of this video, and they obviously do not endorse this technique.

I'm so glad this is considered a hrad math problem, realized I can spend more time on my english

[CarolinaCollegePrep1]

@Kalekenov ~ Congrats on your math skills! That said, please take a look at this problem before assuming the Math Section will be a piece of cake. There are typically 4-6 of this type on every SAT, and they cause even good math students to stumble.

A pipe with a radius of y, can fill a swimming pool in x hours. Assuming the maximum flow of water through the pipe at all times, what part of the pool will be filled in z hours?

a. y + (xz)

b. yz/yx

c. zy/x

d. yz + yx

e. zx/2y

@CarolinaCollegePrep1 and the correct one'll be the one with the same answer I go: 20.

[CarolinaCollegePrep1]

@TheTico305 ~~~ Very VERY Nicely done! The process of exchanging the variables for numbers is a crucial skill we train in our DVD series, and you have done exactly what we'd recommend. Keep in mind however that "occassionally" random plug-ins will often generate what appear to be multiple postive outcomes (in other words, it may appear that A and D both work ~~~ but only one of those will be right). In the example problem above, this did not occur, but it often does. Good luck on your SAT!

@CarolinaCollegePrep1 is it E, and I can u make some videos on ones with hard word problems?

[CarolinaCollegePrep1]

@rampotown Word problems (especially the hard ones) are exhaustively covered in the 5-Disk DVD packet. The best part is that with our system, even the most difficult word problems can be solved with 4th grade math. As to the "answer E" ~ assuming you are speaking to the problem about the pipe filling the swimming pool (see my reply to Kaleknov's comment), then "no" the answer is not "E." Still in our system, we show you how to work this problem also with 4th grade math skills. Best, Coach W.

were you serious when you said that MIT or Harvard students had difficulty with problems like this?

[yungpatt1]

THANKS ALOT!!! THIS VIDEO REALLY BROUGHT IT ALL HOME AND BRIGHTEND MY UNDERSTANDING.:-)

[DumbAndLethal]

@CarolinaCollegePrep1 The answer would just be z/x I think not yz/yx because the y's would cancel out.

[TheTico305]

@CarolinaCollegePrep1 B) I used values y=10, x=10 and z=2, you just need to know that x (the total number of hours) is the 100% of the of the pool and z ( less hours than x) is the part that would be filled. the value of y doesn't matter, you only need to give a value to x and z, (y is eliminated because it is divided by itself: (yz/yx) I first solved that z is 20% of the whole pool, I just plug in the number to all the variables with the numbers I used to solve

[CarolinaCollegePrep1]

@lildarkkill ~~ Okay ~ this IS difficult for most people. In fact, the problem receives the most difficult rating of problems in the math section according to College Board (the guys that design the SAT). If 100 college bound kids were given the question and 2 minutes to work it, only 20 or so would be able to get it correct. With my system, even a 5th grader could work the problem correctly ~ as we eliminate the algebra.

You will need to take the SAT or ACT to gain college admissions.
