    Well first it'd be good to figure out what the 5(14-2)^2 bit is, lemme calculate that real quick.

    I got 120. Is that right? With that, it's now 120/2. Simplified, 60/1.

    Following pemdas, you'd do parenthesis first so "14-2" then exponent, so 12^2, which is 144. Then multiply by 5, you get 720.
