75 + -63 + 7( 115/ -5 + (-8)2 )
-63 is -6 to the third power and (-8)2 is (-8)to the 2nd power. I got 15913 I think that that is wrong and my calculater wouldn't fit all the numbers so I don't know how to check it! Can you please try it so I can double check answers?
it is wrong. You don't have to do it all in your calculator. Do pieces, then add them.

Let's break down the expression step by step to see where the mistake might have occurred.
Given expression: 75 + -63 + 7(115/-5 + (-8)^2)
Step 1: Evaluate the exponents.
(-8)^2 = (-8) * (-8) = 64
Step 2: Simplify the division.
115 / -5 = -23
Step 3: Evaluate the expression inside the parentheses.
115 / -5 + (-8)^2 = -23 + 64 = 41
Step 4: Calculate the multiplication outside the parentheses.
7 * 41 = 287
Finally, add up all the values:
75 + (-63) + 287 = 299
So, the correct answer is 299.
