what are the multiples of 5
Multiples of 6 that are less than 36 are: 6, 12, 18, 24, and 30.
infinite; positive are 9
Leaving out non-positive multiples, the answer is 5, 10, 15 and 20.
Here are all 13 of them: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195
That would be equal to the sum of all positive integers less than 1000 minus the sum of all positive multiples of three that are less than 1000. That would be equal to: (1000 + 1) * (1000 / 2) - 3 * (333 + 1) * (333 / 2) = 1001 * 500 - 1000 * 166.5 = 500500 - 166500 = 334000
