7th Grade Unit 2 Math Vocabulary List 2
Term: A number, a variable, or a product of numbers and variables.
Algebraic Expression: A mathematical phrase involving at least one variable
and sometimes numbers and operation symbols.
Coefficient: A number multiplied by a variable in an algebraic expression.
1. Equation: A mathematical sentence that contains an equal sign.
Order of Operations: The rules to be followed when simplifying
expressions
3. Linear Equation: An equation whose solution is a straight line.
5.
6.
Variable: A letter or symbol used to represent a number.
Like Terms: Terms in an algebraic expression that have the same variable
raised to the same power. Only the coefficients are different.
7. Constant: A quantity or term that does not change its value. It does not have
a variable.
8. Base (of a Power): The number or expression used as a factor for repeated
multiplication.
9. Exponent: The number of times a number or expression (called base) is used
as a factor of repeated multiplication. Also called the power.
10. Evaluate: To find the value of an expression by replacing each variable in an
expression with numbers.
2. Inverse Operation: Pairs of operations that undo each other.
4. Solution: A number (or ordered pair of numbers, or set of numbers) that produces a
true statement when substituted for the variable(s) in an equation or inequality.
5. Inequality: Any mathematical sentence that contains the symbols > (greater than),
<(less than), <(less than or equal to), or > (greater than or equal to).

Addition Words- and, increased, more, more than, plus, sum, total
Subtraction Words- decreased, difference, less, less than, lower than, minus
Multiplication Words- triple, half, product, times, double, twice
Division Words- into, by, among, quotient,
Factor: When two or more integers are multiplied, each integer is a factor of the
product. "To factor" means to write the number or term as a product of its factors.
