What is an algebraic expression?

​a mathematical phrase containing numbers (terms), operation symbols (like +, -, ×, ÷), and variables (like x or y) without an equal sign.

​Objective

Write, read, and evaluate expressions in which letters represent numbers in real-world contexts.

a. Interpret a variable as an unknown value for any number in a specified set, depending on the context.

b. Write expressions to represent verbal statements and real-world scenarios.

Learning Target
