Question

To find sum of three numbers 14,27 and 13, we can have two ways

(a) we may first add 14 and 27 to get 41 and then add 13 to it to get the total sum 54 or

(b) We may add 27 and 13 to get 40 and then add 14 to get the sum 54 Thus, (15+27) + 13 = 14 + (27 +13) ​

To find sum of three numbers 14,27 and 13, we can have two ways :

Mᴇᴛʜᴏᴅ - ❶

(a) we may first add 14 and 27 to get 41 and then add 13 to it to get the total sum 54

Mᴇᴛʜᴏᴅ - ❷

(b) We may add 27 and 13 to get 40 and then add 14 to get the sum 54

Thus,

➾ (15+27) + 13 = 14 + (27 +13) = 54

Answer 2

For any three whole numbers a,b and c,

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

Solution

The given statements can be done for any three numbers.

This property is called the associativity of the addition of numbers. The associative property states that

The addition follows associative property i.e. regardless of how numbers are parenthesized the final sum of the numbers will be the same. Associative property of addition states that:

(x+y)+z = x+(y+z)

Solution: `a+b+c` `a+(b+c),(a+b)+c` association of addition.

Answer:$27 + 1 = 40 \ \ \ and \: then \ \ \ 40 + 14 = 54$
