Question
If a = -8, b = -7, c = 6, verify that (a + b) + c = a + (b + c).
✓
Answer
(a + b) + c = (-8 + (-7)) + 6 = -15 + 6 = -9
a + (b + c) = -8 + (-7 + 6) = -13 + (-1) = -9
Hence, (a + b) + c = a + (b + c) [i.e., Property of Associativity]
a + (b + c) = -8 + (-7 + 6) = -13 + (-1) = -9
Hence, (a + b) + c = a + (b + c) [i.e., Property of Associativity]
