Answer: 41
Step-by-step explanation: It's very easy to make mistakes in order of operations problems if you try to do too much of the problem in your head. It really is worth the extra time it takes to write out every step.
In this problem, simplify (2³ + 11) first because it's located inside the parentheses and always simplify inside the parentheses first.
2³ is just 2 · 2 · 2 or 8.
So our second step reads (8 + 11) · 2 - 8 + 11.
Since we still have parentheses, we still have to simplify what's inside.
8 + 11 is 19.
So our next step reads 19 · 2 - 8 + 11.
According to PEMDAS, multiplication come before addition and subtraction.
So our next step is to multiply 19 · 2 to get 38.
So we have 38 - 8 + 11 which then simplifies to 41.
