Some people confuse the shorthands for repeated addition and repeated multiplication.
The purpose of this section is to give you plenty of practice, so you won't confuse the two!
Exponents give a shorthand for repeated multiplication.
For example,

That is,
$\,(\text{blah})^3\,$ represents three factors of blah.
Here are some examples:
Multiplication by an integer gives a shorthand for repeated addition.
For example,
$\,3(\text{blah}) = \text{blah} + \text{blah} +\text{blah}\,$.
Here are some examples:
