Answer 1

Answer:

associative property of addition

Step-by-step explanation:

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

3+3=1+5

6=6

Answer 2

SOLUTION

CORRECT 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

EVALUATION

Here the given expression is

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

Associative property under addition for the set of Real numbers states that for three Real Numbers a , b , c

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

Now we take a = 1 , b = 2 , c = 3

Then above becomes

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

Hence the property applied is associativity of addition

FINAL ANSWER

Hence the correct option is

(b) associativity of addition
