Variable: A letter (like x or n) that represents an unknown number.
Expression: A math phrase with numbers, variables, and operations but NO equal sign (e.g., 3x + 5).
Equation: A math statement with an equal sign showing two expressions are equal (e.g., 3x + 5 = 14).
Coefficient: The number multiplied by a variable. In 7y, the coefficient is 7.
Constant: A fixed number in an expression or equation that doesn't change (e.g., the 5 in 3x + 5).
Term: A single number, variable, or product of numbers and variables separated by + or − signs.
Like Terms: Terms with the same variable raised to the same power; they can be combined (e.g., 3x and 5x).
Evaluate: To find the value of an expression by substituting numbers for variables.
Simplify: To combine like terms and perform operations to write an expression in its simplest form.
Order of Operations: The rules for which operations to do first: Parentheses, Exponents, Multiply/Divide, Add/Subtract (PEMDAS).
Inequality: A statement comparing two values using symbols like <, >, ≤, or ≥ (e.g., x > 5).
Solution: The value of the variable that makes an equation true.
Distributive Property: a(b + c) = ab + ac — multiply the outside number by each term inside the parentheses.
