Three numbers that equal 500 could be 200, 200, and 100. If you add these numbers together (200 + 200 + 100), the sum is 500. Alternatively, any combination of numbers that adds up to 500 would also work, such as 250, 250, and 0.
We're not quite sure what the "2 digit numbers of 100" are.Do you mean all the "2-digit numbers you say as you count to 100" ?If that's it, then here's how to sum them:There are 100 of them, minus (1 through 9, and 100) = 100 - 10 numbers = 90 numbers.Make pairs of them . . .10 + 99 = 10911 + 98 = 10912 + 97 = 10913 + 96 = 10914 + 95 = 109..etc.There are 45 pairs, and every pair adds to 109.So the sum of all 90 numbers is (45 x 109) = 4,905.
