thanks that was it 7*(4*10-7squared) +4 = -59 Iam trying to learn what order i do these to help my son

PEMDAS is the hierarchy of operations

Parentheses...exponentiation
...multiplication...division
...addition...subtraction

things in parentheses 1st
... 7^2 = 49
...4 * 10 = 40
...40 - 49 = -9

7 * -9 = -63

-63 + 4 = -59
