Document Summary
Operations that do the exact opposite of each other; they undo each other (addition and subtraction, for example) The property that states that if you multiply both sides of an equation by the same number, the new equation will have the same solution. Numerical expression an expression that includes numbers and operations. Order of operations the order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction. A number produced by raising a base to an exponent. Subtraction property of equality if you subtract the same number from each side of an equation, the two sides remain equal. Term numbers and variables separated in an expression by a + or - Variable a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity. The distance a number is from zero on a number line.
