Using PEMDAS...

4 x 4 + 4 x 4 + 4 - 4 x 4 =
(16) + (16) + 4 - (16) = 

36 - 16 = 20

Your answer is 20, not 320.

You must multiply before you add and subtract

no you are incorrect to do this problem use PEMDAS so 4 x 4 = 16 + 4 x 4 = 32 + 4 - 4 x 4 so do 4 x 4 first and you get 32 + 4 - 16 and simplify to get      36 - 16 which is 20. So the answer is 20 =)
