90/(10+(3^2-4))
PEMDAS
Parentheses, exponents, multiplication, division, addition, subtraction
First, we would solve what's in the parentheses. However, since we have more than one set of parentheses and a value in the parentheses has an exponent, we'll do that first. Then, we can do the addition inside the parentheses.
90/(10+(9-4))
90/(10+(5))
90/(10+15)
90/(25)
Now, we can finish the problem by doing division.
90/25
18/5
3.6
