# Use the associative property of addition to find the total of 1, 10, and 18 in two different ways.

Whole numbers are the set of natural number including 0. Addition is associative for whole numbers.

## Answer: The total of 1, 10 and 18 in two ways is the same as 29.

Let's find the associativity of whole numbers in addition.

**Explanation:**

The associative property of whole number says

a + ( b + c ) = ( a + b ) + c [∀ a, b and c ∈ W]

Let a = 1, b = 10 and c = 18.

⇒ 1 + ( 10 + 18) = ( 1 + 10 ) + 18

By appliying BODMAS rule, we get

⇒ 1 + 28 = 11 + 18

⇒ 29 = 29

LHS = RHS
