Don't understand the reminder, how is that possible 25%7 runs 4, and 20%7 runs 6?

Answer 1

25 / 7 = 3 --> rest 4
20 / 7= 2 --> rest 6
To get the rest of a division use the mod operator
25 % 7 = 4
20 % 6 = 6

If a number is divisible by another for example 4/2 = 2 --> 4% 2 = 0

Answer 2

So simple, thank you Denise
