Answer 1

Since the value of y is 2, x + y equals to 19. Then using the modulo operator gives you remainder of 19/4, which is 3.

Answer 2

19/4
=4 remainder 3

So, 19%4=3

Answer 3

If you divide 19 by 4, remainder is 3 (19=4*4+3), it's saying that .Here % (called ''Modulus'' operator) is used to express this operation.

Answer 4
