LIKE TERMS > Have the same variable AND exponent!
To "simplifying" polynomials, is to group "like" terms
Degree of a polynomial
Monomial, binomial, trinomial

Look at this example of addition of polynomials. This is the "horizontal" method. Notice how the brackets are eliminated,, followed by the pairing of like terms.
The vertical method:
Here are the steps mentioned in the notes:
Look at the following example:
Look at the following examples of the addition of polynomials using algebra tiles, and pay attention to the making of "zero pairs":
Here is an example I put together using the algebra tiles in the classroom:
