addition property of equality: Adding the same number to each side of an equation produces an equivalent expression.
additive inverse: The sum of a number and its additive inverse is zero.
algebraic expression: A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.
cube root: One of three equal (identical) factors of a given number.
decimal expanison: non-negative real number x will end in zeros (or in nines) if, and only if, x is a rational number whose denominator is of the form 2n5m, where m and n are non-negative integers.
equation: A mathematical sentence that contains an equals sign.
evaluate: To find the value of an expression by replacing each variable in an expression with numbers.
exponent: The number of times a number or expression (called base) is used as a factor of repeated multiplication. Also called the power.
exponential notation: a method in mathematics that allows the representation of numbers in shorter form and aids in mathematical calculations.
inverse operation: Pairs of operations that undo each other.
irrational: A number whose decimal form is nonterminating and nonrepeating. Irrational numbers cannot be written in the form a/b, where a and b are integers (b cannot be zero). So all numbers that are not rational are irrational.
like terms: Terms in an algebraic expression that have the same variable raised to the same power. Only the coefficients of like terms are different.
multiplication property of equality: States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal.
multiplication inverse: or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity
perfect square: A number that is the square of a whole number.
radical: "the bth root of a," is called a radical.
rational: A number that can be written as a/b where a and b are integers, but b is not equal to 0.
scientific notation: A way to express a very large or very small number as the product of a number between 1 and 10 and a power of 10.
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.
solve: find an answer to, explanation for, or means of effectively dealing with (a problem or mystery).
square root: One of two equal factors of a given number.
variable: A letter or symbol used to represent a number.
