METHOD ONE: Add and Multiply - The most obvious thing you can do is add the
numbers in the parentheses and then multiply that sum by the number
following the multiplication sign.
( 7 + 1 ) x 6 =
8 x 6 = 48
METHOD TWO: Distributive Property - The distributive property says that we
can multiply first and then add, like this:
( 7 + 1 ) x 6 =
7 x 6 + 1 x 6 =
42 + 6 = 48
You can solve these problems either way. Actually it's best to use both
methods and to learn to recognize problems which are easier with each
method.
