Answer 1

9514 1404 393

Answer:

D

Explanation:

Your calculator* can tell you the answer to this. Each expression is evaluated according to the order of operations.

A: 6 + 4/3·3 = 6 +(4/3)·3 = 6 +4 = 10

B: (6 +4/2) -1·3 = 6+2-3 = 5

C: 6 +(4/2) +1·3 = 6 +2 +3 = 11

D: (6 +4)/2 -1·3 = 10/2 -3 = 5 -3 = 2

_____

* If your calculator doesn't properly use the Order of Operations, you should get one that does. The calculator behind the Go.ogle search box reliably uses the order of operations, so you can use it if your own doesn't work properly.
