Question

Apply the rules for order of operations to simplify (2− 1) + 32 ÷ 3. A. 6 B. 10/3 C. 3 D. 4

Answer 1

B, I think is your answer. 

Answer 2

Use this: PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
Lets try.
I see a parenthesis. (2-1) solve that.
It will be:
1+33/3
Division comes before addition.
So do 33/3= 11
Now do 11+1= 12
12 is your final answer.
