Question

If you rewrite the problem 14(22) as 14(20+2) so that you can use mental math, which of the following properties will you use?

*nevermind I got it*

Answer 1

For this case, the property you can use is the following:
Commutative property.
We have then that:
14 (20 + 2) = 280 + 28 = 308
Equivalently:
14 (2 + 20) = 28 + 280 = 308
Either way the result is exactly the same.
Answer:
Commutative property.
