I'm confused about how the % is used in the division of numbers. Can someone please elaborate?

hi. i am having some confusion with the boolean. It seems as though it was used for the division. i thought that was the job of the forward slash? Can someone break down that part of the code for me? Thanks a lot.

Hi,

I'm unable to watch the video at the moment but I will try and help.

That symbol is called Modulo and it returns the remaining of the division. 7%2 will return 1 because 7/2 is 3 and some more (1). 8%3 will return 2 but 8%2 will return 0, since 8/2 is 4 without remainder.

It's mostly used to check if a number is even or odd (n%2 - if it returns 0 its even, if it returns 1 it's odd. n%2 can't return any other value) but you can find it's usage in many other ways.

Hope I clarified it. Have fun!
