you would add -7.
76
its 30 because you add 8 and 7 then add it by itself or multiply it by 2**.**
(7*8)+(7+8) = 56+15 = 71
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.
You get the largest sum if you add all of the numbers.
It means to add. For example, if you are told to take the sum of 5 and 8, you would add them together.
The sum of 8 and 6 is 14. Therefore, if you add this to ( n ), the total would be ( n + 14 ).
4+7+5+6+8=30 30 is the only sum those numbers can add up to.
The sum of 1 and 7 is 8. That is, 1 + 7 = 8
You add two addends to get a sum. For example, in 3 + 5 = 8, 3 and 5 are addends, and 8 is the sum.
Just add the real part and the imaginary part separately.
11. Sum means to add 3+8=11
