The remainder is always smaller than x.

x is a positive integer.
For example,
1 divided by 11, the remainder is 1
2 divided by 11, the remainder is 2
3 divided by 11, the remainder is 3
....
10 divided by 11, the remainder is 10
11 divided by 11, the remainder is 0
12 divided by 11, the remainder is 1

#remainders are in the repeat of 0,1,2,3,4,5,6,7,8,9,10

Therefore, Quantity A < Quantity B (11)
