Ineed with this problem i would like the answer to be step be step
(9- 2^2 + 10 * 8) divide by 8

First, you would need to "simplify" the problem as I say, so put the whole parenthesis part of the equation on the top and the 8 on the bottom. then turn the two into a 4 because you need to get rid of the power. After that subtract 9 and 4 to get 5, add by ten and you get 15. Now, you may say why would I get 15? what about the to eights, well you would need to cross them out of the problem because if you multiply 8 by 15, you get 120, then divided by 8 would equal 15 again, so it would be much more simple.
Hope this helped!

The range would be 13 because you’re finding the difference
