All of the serious answers above are correct, but if you're trying to verify the distributive law,
(8 - 5)(11 + 7) =
88 + 56 - 55 - 35 =
88 + 1 - 35 =
54

(8-5)(11+7) = X
8-5 = 3 11+7 = 28
(3)(28) = 3 x 28
3 * 28 = X
84 = X

Follow this so you know the order in which to do operations.
Hence brackets..... (8-5) = 3 and (11+7) = 18.
Then multiply the two brackets.....3 x 18 = 54

the answer is 54.
IN a problem like this, you do what is in the paranthesis first. (have u heard of pemdas??) It is the order of operations in which you would follow when solving a problem in algebra. Parentheses, Expontents,Multiplication, Addtion, Subtraction. You start from the left. Since it is the numbers are in parennthese, you solve them first. YOu will get (3)(18). Then you multiply. 3 x 18 =54. YOu can remeber pemdas by saying Please Excuse MY Dear Aunt Sally.
