Question

Shilo is trying to compute the value 27+55+13 she adds 27+13 to get 40 and than add on 55 which of the following properties is shilo using

Answer 1

Shilo is using the associative property.

The associative property states that the grouping of numbers in addition does not affect the sum. In other words, (a + b) + c = a + (b + c).

In this case, Shilo could have grouped the numbers differently, such as adding 55 and 13 first, and then adding 27. However, regardless of which numbers she grouped first, the final sum would still be the same.

Therefore, Shilo is taking advantage of the associative property to efficiently calculate the sum.
