Your answer is 10. Work ____ You can use Please Excuse My Dear Aunt Sally because this is order of operations. It stands for parenthesis meaning you do whatever is in the parenthesis first. Then exponents. Then, multiplication and division in whatever other they appear. Lastly, you do addition and subtraction in whatever other they appear.  Since 51 + 3 is in the inner parenthesis, you do it first. You get 54 Now you are left with (54 - 3^2)/ 9 * 2 Now since there are exponents inside the parenthesis, you do this first and you get (54 - 9 )/ 9 * 2 Now you must finish off your parenthesis and subtract 54 - 9 and you get 45 / 9 * 2 Next you work left from right solving the equation. 45/9 equals 5 5 * 2 equals 10.
