TermDefinition
absolute value the distance between a number and zero on a number line

whole number the set of natural (counting) numbers and zero
volume a measurement of the space that would fill an object
additive inverse the opposite of a number
algebraic expression contains numbers, variables, and operations
area a measurement of the space an object covers
associative property a(b x c) = (a x b)c OR x + (y + Z) = (x + y) + z
