I need definitions

Question

Since i study math in french, i just need to know what everything actually means

Answer 1

like for python, whats // and %

Answer 2

% is modulus like a%b here you just keep subtracting untill you get a number between 0 and b
for example
4%2=
4-2=2 (2 is still equal or greater than 2)
2-2=0 (the modulus here is 0)

another one

13 % 4
13>=4? (true)
13-4=9
9>=4? (true)
9-4=5
5>=4? (true)
5-4=1
1>=4? (false)
modulus = 1
