What is the Sum of the positive non-multiples of three that are less than 1000?
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
How many positive integers less than 1000 are there such that the digits are not strictly increasing order from left to right?
