Distributive Property of Mutiplication over Addition

The distributive property of mulitplication over addition is written as `a(b+c)=ab+ac`. For example:

`3(x+2)=3x+6`
The opposite of distribution is factoring where we go backward. For example:

`3x+3y=3(x+y)`

In an expression like `6s+6t+6w`, the `6s`, `6t` and `6w` are called terms. Like terms are terms with like variables THAT HAVE THE SAME EXPONENT!

You can collect like terms, for example:

`6y^2+2y^2` is the same as `8y^2`

and `4x^3+5x^3` is the same as `9x^3`
