Question 1143620
<pre>
The above answer is wrong.

We cannot use the distributive law.

We must use the rule of PE(MD)(AS) or

{{{matrix(1,4,

P,E,matrix(2,1,M,D),matrix(2,1,A,S))}}}

We do what's in the parentheses first.
Since 2+2 is in the parentheses, we must do that first,
and get 4.  So we replace 2+2 by 4. Now we have: 

8÷2(4)

Now there is nothing to do in the parentheses.

There are no exponents.

We look for the first multiplication or division going left to right.
(Neither multiplication nor division necessarily comes before the
other, we must do whichever one comes first going left to right.

That's 8÷2.  So we do that and get 4. So we replace 8÷2 by 4

4(4)

There is nothing to do in the parentheses, and there is only the
multiplication 4(4) left, so the final answer is

16.
