A

Absolute Value: The distance of a number from zero on the number line, always positive.
Acute Angle: An angle that measures less than 90 degrees.
Addition: The process of combining two or more numbers to get a total or sum.
Algebra: The branch of mathematics that uses letters and other symbols to represent unknown numbers.
Algebraic Expression: A mathematical phrase that can contain numbers, variables, and operators but doesn’t have an equals sign.
Algebraic Fraction: A fraction that contains algebraic expressions in the numerator, denominator, or both.
Algebraic Term: A number, variable, or product of numbers and variables.
Alternate Angles: Angles that are on opposite sides of a transversal and are outside the two lines.
Angle: The measure of the amount of rotation needed to bring one line or plane into coincidence with another.
Area: The measure of the extent of a surface, usually expressed in square units.
Arithmetic Mean: Another term for the average, calculated by adding up a set of values and dividing by the number of values.
Asymptote: A line that a curve approaches but never touches, especially as it extends towards infinity.
Average: The sum of a set of values divided by the number of values.
Axis: A reference line from which distances or angles are measured in a coordinate grid.
Axis of Symmetry: A line that divides a figure into two halves that are mirror images of each other.
