so i kno the formula for the for the sum of the first N positive integers
when i = 1
The Attempt at a Solution
i kno the answer = n^2(n+1)/2
but could someone explain step by step how you reduce it to get the final answer? as if i'm in kindergarten? i'm slow, thanks.
following the formula: n(n+1)/2 * n(n+1)/2 * n(n+1)/2 ?
i don't understand how to reduce the terms to get the final answer provided
