Vocabulary Definition Example Commutative 18 + 9 = 9 + 18 You can add or Property multiply numbers in 15 x 2 = 2 x 15 (Ordering) any order When you are only Associative adding or only (17+2)+9=17+(2+9) Property multiplying, you can (Grouping) group any of the (12x2)x4=12x(2x4) numbers together. The sum of any Identity Property of number and zero is Zero 9+0=9 equal to the number (addition) (addition) The product of any Identity Property of number and one is One 5x1=5 equal to the number. (multiplication) (multiplication) The product of any Property of Zero number and zero is 7x0=0 (multiplication) zero.
