Some special sums - Undergrad Mathematics Comment: to establish the formula for the sum of squares, we would start out with the cubic equation and go through a very similar procedure to the one we used for Gauss's formula. Similarly, to establish the formula for sums of cubes, we would use as a s
10.2 Linear Growth - Austin Community College - Start Here. Get There. Now think about pairing them: 1 with 100 2 with 99 3 with 98 . . . 48 with 53 49 with 52 50 with 51 Each pair adds up to · ·. How many pairs? · · So the total is 50 x 101 = · ·. Karl did it with 1 multiplication, not 100 additions! His formula for the sum
