5 True/False questions
inequalities → mathematical sentences containing <,>,≥, or ≤ are called these.
Associative property of addition → For any number a and b,
a + b= b + a
Property of additive inverses → For each rational number a, there is one and only one rational number -a such that a + (-a) = 0
Commutative property of addition → For any number a,b and c,
a + (b + c)= (a + b) + c
Property of Multiplicative Inverse → For each nonzero rational number a, there is one and only one rational number 1/a such that a * 1/a = 1. AKA: reciprocal
