It might be wrong, but here take it this way with Pemdas.
P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal = 8040 using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.
