How i calculate 2%3 and 3%2

Question

I think 3%2 =1
But 2%3=2 ?!

Answer 1

Modulo operator returns the remainder.
So 2%3 is 2 because 2 is not divisible by 3 and 2 is the remainder.

Answer 2

0%3 = 0
1%3 = 1
2%3 = 2
3%3 = 0
4%3 = 1
5%3 = 2
6%3 = 0
7%3 = 1
8%3 = 2
9%3 = 0

Answer 3

modulo is pretty much

2%3 = 2 - (2 / 3)

it returns the remainder of division. i.e.
9 % 2 = 1
9 - (9 / 2) = 1

To answer your question:
3-(3/2)=1
2-(2/3)=1
