Algebraic expressions contain numbers, variables, and operators and can be simplified using the distributive property and by combining like terms. The document provides examples of algebraic expressions that can be simplified by first distributing all terms inside parentheses and then combining like terms, such as 3(4n + 2) + n, which is simplified to 12n + 6 + n = 13n + 6.

R.1 simplifying expressions
Algebraic Expression a mathematical phrase that can contain numbers, variables (like x or y) and operators (like +, -, x, 歎 ). Like Terms terms that have the same variables and powers. (The coefficients do not need to match.)
Distributive Property When we use the distributive property, we are multiplying each term inside the parentheses with the term outside of the parentheses.
First, distribute to get rid of all parentheses. Then, combine like terms.
