Add and check your sum by changing order. 1. T O 8 + 3 7 + 2 3 Check T O 2. T O 1 8 + 2 4 + 2 8 Check T O

To solve the given problems, we'll perform the addition for each and then verify our calculations by rearranging (changing the order) and summing again.
Problem 1

Calculate the Sum:
108 + 37 + 23 = 168

Check by Changing Order:
Let's add them in a different order:
37 + 23 + 108 = 168
Both orders give the same result, confirming our sum is correct for this problem.


Problem 2

Calculate the Sum:
18 + 24 + 28 = 70

Check by Changing Order:
Let's add them in a different order:
24 + 28 + 18 = 70
Both computations again confirm that our sum is correct for problem 2, as rearranging the order of addition did not change the result.


This process of adding numbers and then checking by changing the order demonstrates the commutative property of addition, which states that numbers can be added in any order without changing the sum.
