Properties Beat the Computer Drill
Directions • A slide will appear showing an equation which illustrates a property. • Say the property aloud before the computer can answer (6 sec). • You will hear a sound when the slide changes.
Commutative Property for Addition a + b = b + a
Distributive Property ab + ac = a(b + c)
Commutative Property for Multiplication a b = b a
Multiplicative Identity Property a 1 = a
Additive Identity Property a + 0 = a
Associative Property for Multiplication (a b) c = a (b c)
Associative Property for Addition (a + b) + c = a + (b + c)
Additive Inverse Property a + (-a) = 0
Distributive Property a(b + c) = ab + ac
Multiplicative Property of Zero a 0 = 0
a = 1 1 a
1 a = 1 a Multiplicative Inverse Property
Addition Property of Equality If x = b, then x + c = b + c
Multiplication Property of Equality If x = b, then x c = b c
Symmetric Property of Equality If a = b, then b = a
Transitive Property of Equality If a = b, and b = c, then a = c
Substitution Property of Equality If x = 3, then 5x = 15
