Common Core Standards
Arithmetic with Polynomials and Rational Expressions
Once students are comfortable with the structure of the algebraic language, they can start forming sentences, both simple and a little more complicated. And with algebra, as with any language, there are many different ways to say the same thing.
These standards discuss how to work with polynomials and rational expressions, combine them, separate them, and even rearrange them. By the time these standards are satisfied, they'll be juggling them, too.
