Monomials – Addition / Subtraction Monomial - a single term item that is a variable or constant. They can contain many variables or be combined.

Monomials – Addition / Subtraction

** notice there are NO addition or subtraction signs separating any of the numbers or variables.

Monomials – Addition / Subtraction ** notice there are NO addition or subtraction signs separating any of the numbers or variables. ** ALSO, numbers that appear in front of variables not separated by an addition or subtraction sign are called coefficients.

Monomials – Addition / Subtraction

We can add and subtract LIKE variables.

Monomials – Addition / Subtraction We can add and subtract LIKE variables. Like variables look exactly the same except for their coefficients.

Monomials – Addition / Subtraction

** when variables are not in alphabetical order, I like to rewrite the monomial in alphabetic order to find my like variables…

Monomials – Addition / Subtraction - Exponents MUST be the SAME

Monomials – Addition / Subtraction - Exponents MUST be the SAME - ALL letters must match
