Question 1.
Take set of 3-3 numbers and test properties (RBSESolutions.com) of associativity on the operations of addition and multiplication respectively.
Solution.
Adding under associativity
(22 + 7) + 6 = 29 + 6 = 35 or 22 + (7 + 6) = 22 + 13 = 35
∴ In addition, associativity occurs.
Multiplying under associativity
(22 × 7) × 6 = 154 × 6 = 924 or 22 × (7 × 6) = 22 × 42 = 924
∴ In multiplication, associativity occurs.
