Question

(1 + 2) + 3 = 1 + (2 + 3) The above is known as (a) commutativity of addition (b) associativity of addition (c) commutativity of multiplication (d) associativity of multiplication.

Answer 1

Step-by-step explanation:

Associativity of addition

They can be added in any order

All Stay Same Order

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

(1 + 2) + 3 = 1 + (2 + 3) The above is known as

(a) commutativity of addition

(b) associativity of addition

(c) commutativity of multiplication

(d) associativity of multiplication.

EVALUATION

Associative property under addition states that for three Real Numbers a , b, c

( a + b ) + c = a + ( b + c )

Let us take a = 1 , b = 2 , c = 3 we get

(1 + 2) + 3 = 1 + (2 + 3)

So the property used is associativity of addition

FINAL ANSWER

Hence the correct option is (b) associativity of addition
