3+2^3-8+2 write it down in numbers
3+8-8+2 do the powers(exponents)
3+0+2 the 8s cancel each other out
3+2 get rid of the zero
and if you need help with this step you are in the 1st grade okay

The way you wrote the problem is confusing, it could be:
(3+2)^3 - (8+2)^2 in which case you should say 'quantity'.
But taking what you wrote:
3+2^3-8+2^2
Work out the exponents (powers) first:
3+8-8+4 = 3+4 = 7
