Vocabulary

	Commutative Property of Addition	A mathematical property that states that the order in which quantities are added does not matter.  The commutative property of addition is sometimes called the rearrangement property of addition.
	Commutative Property of Multiplication	A mathematical property that states that the order in which quantities are multiplied does not matter.  The commutative property of multiplication is sometimes called the rearrangement property of multiplication.
	Distributive Property	A mathematical property used to rewrite expressions involving addition and multiplication.  The distributive property states that for any three quantities a, b, and c, a(b+c)=ab+ac.  If an expression is written as a factor multiplied by a sum, you can use the distributive property to multiply the factor by each term in the sum.  If an expression is written as a sum of terms and the terms have a common factor, you can use the distributive property to rewrite the expression as the common factor multiplied by the sum.  This process is called factoring.
	Equivalent Expressions	Expressions that represent the same quantity.
	Expanded Form	The form of an expression made up of sums and differences of terms rather than products of factors.
	Factored Form	The form of an expression made up of products of factors rather than sums or differences of terms.
	Parabola	The graph of a quadratic function.  A parabola has a line of symmetry that passes through the maximum point if the graph opens downward or through the minimum point if the graph opens upward.
	Roots	The roots of an equation are the values of x that make y equal to 0.  The roots of an equation are the x-intercept of its graph.
	Term	An expression with numbers and/or variables multiplied together.  Terms are separated by an addition or subtraction sign.
