Question

11. Consider the sum 28 + (-15) + 22. (Lesson 1)

A. What property of addition could be used
to write the integers in a different order?
Explain why it might be beneficial to
reorder the integers to find the sum.
B. Find the sum 28+ (-15) + 22.

Answer 1

The commutative property of addition can be used to write the integers in a different order. Reordering the integers may simplify the calculation process. The sum of 28 + (-15) + 22 is 35.

Step-by-step explanation:

The property of addition that could be used to write the integers in a different order is the commutative property. This property states that changing the order of the numbers being added does not change the result. Reordering the integers in this sum may be beneficial in the context of mental math, as it can simplify the calculation process.

Using the commutative property, we can rewrite the sum 28 + (-15) + 22 as (-15) + 28 + 22. Now we can add the integers together to find the sum: (-15) + 28 = 13, and 13 + 22 = 35. Therefore, the sum of 28 + (-15) + 22 is 35.
