Question

Simplify this expression 7(6y)

Answer 1

42y

Know that you can multiply these numbers in any order or grouping thanks to the associative property. So break it down like this

7*(6*y)
7*6*y
--you can switch the order and it will still get you the same answer.--

6*7*y
(6*7)*y
42y

Answer 2

we open the brackets by multiplying the term outside by the term inside.
therefore 7×6y=42y
