 terms with exactly the same variables, including the same exponents like terms a number located to the right of 0 on the number line positive number {0,1,2,3,4,5,...} whole numbers the result of multiplication product angles with the same measure that are formed by intersecting lines vertical angles the opposite of a number additive inverse numbers that are either positive or negative signed numbers the answer to a subtraction problem difference When 0 is added to a number, the number is unchanged. identity element for addition When a number is multiplied by 1, the number is unchanged. identity element for multiplication a number located to the left of 0 on the number line negative number the answer to a division problem quotient the process of using the distributive property to write a sum or a difference as a product factoring {...,-3,-2,-1,0,1,2,3,...} integers the reciprocal of a number multiplicative inverse the numerical factor in a term numerical coefficient a single number, or a product of a number and one or more variables raised to powers term angle that measures 90 degrees right angle a quotient of two quantities with the same units ratio an equation that is true for all replacements of the variable identity angles whose measures have a sum of 180 degrees supplementary angles the number that is a repeated factor when written with an exponent base an angle that measures 180 degrees straight angle a statement that two ratios are equal proportion a number that indicates how many times a factor is repeated exponent (power) Each side of an equation may be multiplied or divided by the same nonzero number without changing the solution. multiplication property of equality a part of the whole amount percentage The same number may be added to or subtracted from each side of an equation without changing the solution. addition property of equality a number written with an exponent exponential expression a symbol, usually a letter, used to represent an unknown number variable the distance between 0 and the number on the number line absolute value pairs of numbers whose product is 1 reciprocals (multiplicative inverses) the answer to an addition problem sum Ax + B = C, for real numbers A, B, and C, with A not equal to 0 linear equation The opposite of a number "a" is the number that is the same distance from 0 on the number line as "a," but on the opposite side of 0. additive inverse (negative) of "a" equations with the same solution set equivalent equations angles whose measures have a sum of 90 degrees complementary angles method that provides a way of determining whether a proportion is true cross products numbers that are nonrational numbers represented by points on the number line irrational numbers numbers that can be written as quotients of two integers, with the denominator not 0 rational numbers include all numbers that can be represented by points on the number line real numbers a statement that says two expressions are equal equation a collection of numbers, variables, symbols for operations, and symbols for grouping algebraic expression any replacement for the variable that makes the equation true solution {1,2,3,4,...} natural numbers
