You can put this solution on YOUR website!
you work from the inner set of parentheses out.
within each set of parentheses, and in the rest of the expression after you've removed all parentheses, you do the following:
do exponents before multiplication and do multiplication before addition.
roots are another form of exponents, so you do both if they are both present, working from left to right.
division is another form of multiplication, so you do both if they are both present, working from left to right.
subtraction is another form of addition, so you do both if they are both present, working from left to right.
expression is:
9 + (4 - (10-9)^2)^3
(10-9) is equal to 1.
expression becomes 9 + (4 - 1^2)^3
1^2 = 1
expression becomes 9 + (4 - 1)^3
4-1 = 3
expression becomes 9 + 3^3
3^3 is equal to 27.
expression becomes 9 + 27
9 + 27 = 36
expression becomes 36
