Question: how many integers from 1 to 100 are multiples of 2 or 3?
Answer: There are 50 multiples of 2 between 1 and 100 (including 100) because 100 divided by 2 is 50. There are 33 multiples of 3 between 1 and 100 because 100 divided by 3 has a quotient 33 and a remainder 1. We know that 2 x 3 = 6.
