There's a nice rule that says, "
If N divided by D equals Q with remainder R, then N = DQ + R"
For example, since 17 divided by 5 equals 3 with remainder 2, then we can write 17 = (5)(3) + 2
Likewise, since 53 divided by 10 equals 5 with remainder 3, then we can write 53 = (10)(5) + 3

GIVEN: When Q is divided by W, the quotient is R and the remainder is E.
So, we can write: Q = WR + E
Which of the following expressions is equal to E?Take: Q = WR + E
Subtract WR from both sides to get: Q - WR = E
Answer: C
