Licemer1 [7]
First, using the order of operations(PEMDAS), you would solve what is inside the parenthesis. 
<span>(8.218 + 9.93) + (17.782 + 0.07)
(</span>18.148) + (17.852)
18.148 + 17.852

Now, all you would have to do is add the two sums. 
18.148 + 17.852 = <span>36
</span>
The answer would be 36.
