 So one of the things we've just seen is that I'm able to do in the basic math And it started to get a little weird because all of a sudden I was doing you know this ten asterisks for two To do exponentials, but as you can kind of see from the screen This way I'm talking about something like division or I've already demonstrated division You might say I can do three slash three and it's okay Well all right three slash four okay, what should that equal well if we kind of look at that That's three going into four zero times with the remainder of three So kind of playing the fractional sense. This should give me 0.75 that's what it does But if you kind of listened to how I was kind of rationale Rationalizing all that for a second. I said three goes into four zero times with a remainder of three so How do I how I kind of Separate this you know, maybe I don't want a decimal point all of a sudden So how can I do what we call integer division? I can take two whole numbers and divide them together and I should only get a whole number back Well, it's kind of the same Approach is going to happen here is I still do the three I still do a slash but instead of doing just one slash going into the four actually put a second slash in Now if I come in with four all of a sudden this is where magically. Oh I get a zero what happens is because I Python it looks at this and goes, okay This is a whole number. This is a whole number Let's divide them and I'm going to just go ahead and truncate throw away Everything decimal wise again. Remember this is storing less in binary So, okay, how do I get the remainder? How do I get that all of a sudden if I want to happen to have the remainder which we'll see in kind of greater practice later on? How do I do that? And so all of a sudden We come to a new symbol you never learned this one in math class Oh, well you do the long division you put an R there and that's how you that's how you represent it Well, no, I'm not able to just do three R for that clearly does not work So all of a sudden we're introduced to a new symbol Modules or modular depending on who you kind of look at and listen to but what this does is it brings out my remainder and so three Percent sign, you know, it's no longer a percentage. If I did three percent in this case What is three percent of forty again in there? That's not how Percentages you work and that's not what the percent sign does inside of Python. So three percent Modulo for again, this is going to give me the remainder. So how many times can Three go into four zero times. It's not big enough. And so what I have as a remainder of three Let's flip those two. Let's go for Modulus three what I'm saying here is I'm saying four divided by three Okay, well three in this case can go into four one time and So now all of a sudden what we're looking at is how many Remainters do we have well in this case we should have one main
