How many ways of adding eight odd numbers together to get 20? - Answers

It is impossible to add eight odd numbers together to get an even sum like 20. The sum of any odd numbers is always odd if an odd count of them is used, and it becomes even only when an even count is used. Since eight is an even number, the sum of eight odd numbers would be even, but it will still exceed 20 since the smallest odd number is 1, and the sum of eight 1s is 8, which is less than 20. Thus, there are zero ways to add eight odd numbers to achieve a sum of 20.
