To determine

To find: which property is used

Answer to Problem 14STP

Associative property of addition is used.

Explanation of Solution

Given: $\left(p+5\right)+13=p+\left(5+13\right)$

Calculation:

Given equation: $\left(p+5\right)+13=p+\left(5+13\right)$

Here, in the given equation, grouping of number is changed.

According to the associative property of addition,

  $\left(a+b\right)+c=a+\left(b+c\right)$

Property is same as equation given in the problem. The associative property states that you can add or multiply regardless of how the numbers are grouped.

Conclusion:

Hence, associative property of addition is used.
