OK, let's check this thing with some real numbers... Just so we can really believe that it works.
First, let's do it the official "order of operations" way... Hit inside those parenthesis first!
Now, let's use the distributive property:
We distribute the 2 to the 3... and, then, to the 4...
Remember the order of operations after that!
Multiplication, then addition!
Yep! We got 14 again. So, it works!
Go ahead and try it yourself with any three numbers. It will always work.
