How is it that 3%5=3?

[1v5E3TCk]

5%2=1
8%2=0
5%4=1

x%y gives you the remainder of x/y

5%2=3

A small correction: this above is equal to 1.

5%2=1 because 5 = 2 + 2 + 1
8%2=0 because 8 = 2 + 2 + 2 + 2
5%4=1 because 5 = 4 + 1
3%5=3 because 3 = 3 (no 5 is added)

[condor]

5%2=1 because 5 = 2*2 + 1 and

3%5=3 because 3 = 5*0 + 3.

Consider its reverse record

3 = 5 * 0 + 3
