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

**Solution:**

The associative property of addition states that when we add, we can group the numbers in any order or combination.

i.e., (a + b) + c = a + (b + c)

From the question, we have to determine the total of 1, 10, and 18 in two different ways.

(i) Let us consider (1 + 10) + 18

By applying the BODMAS rule, we evaluate the sum inside the parenthesis or brackets.

= 11 + 18

= 29

Or

(ii) Let us consider 1 + (10 + 18)

By applying the BODMAS rule, we evaluate the sum inside the parenthesis.

= 1 + 28

= 29

(i) = (ii) Thus in both ways, we determine the sum of 3 numbers as 29.

Therefore, by using the associative property of addition we find that 1 + 10 + 18 = 29.

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

**Summary:**

Using the associative property of addition we find that the total of 1, 10, and 18 in two different ways is 29.
