Find the value of the expression. 128 divided by 4square plus 6 minus 1

i interpreted this as:
128 / 4^2 + 6  1
recall PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. this is the order in which operation must be done first. therefore,
128 / 8 + 6  1
16 + 6  1
11
hope this helps~ :)
