Sometimes in mental arithmetic, calculations are done in a different order because the numbers are more "convenient." For example,

consider the following calculations:

13.2.5 = 26.5 = 130

and

calculations. However, the

13.2.5 = 13 - 10 = 130

The first calculation was performed left-to-right, according to the standard rule for several multiplicati

second calculation is much simpler because it was done in a different order.

Which of the following mathematical properties allows us to do this?

The associative property of multiplication

The commutative property of addition
