PO D State whether the conjecture is true or false. If false, provide a counterexample. Subtraction of whole numbers is associative False (8−5) − 3 ≠ 8 − (5−3)

The Commutative Property states that the order in which numbers are added or multiplied does not change the sum or product. a + b = b + aa × b = b × a

The Associative Property states that the way in which numbers are grouped when they are added or multiplied does not change the sum or product. a + (b+c) = (a+ b) + ca × (b×c) = (a × b) × c

The Additive Identity Property states that when 0 is added to any number, the sum is the number. a + 0 = a0 + a = a

The Multiplicative Identity Property states that when any number is multiplied by 1, the product is the number. a × 1 = a1 × a = a

The Multiplicative Property of Zero states that when any number is multiplied by 0, the product is 0. a × 0 = 00 × a = 0

The Distributive Property states that to multiply a sum or difference by a number, multiply each term inside the parenthesis by the number outside the parenthesis. a( b + c ) = ab + aca( b – c ) = ab − ac

2 ( y + 2) = 2(y) +2(2) = 2y + 4 The expressions 2(y+2) and 2y+4 are equivalent expressions. No matter what y is, these expressions have the same value.
