The equation that exemplifies the Associative Property of Addition is:

4 plus (2 plus 1) equals (4 plus 2) plus 1.

The equation that exemplifies the Associative Property of Addition is:

4 plus (2 plus 1) equals (4 plus 2) plus 1

To understand why this equation represents the Associative Property of Addition, let's break it down:

The Associative Property of Addition states that the grouping of numbers being added does not affect the sum.

In this equation, we have three numbers being added: 4, 2, and 1. By using parentheses to group the numbers differently, we can see that the sum remains the same:

First, let's evaluate the left side of the equation: 4 plus (2 plus 1)

The inner parentheses indicate that we should first add 2 and 1, which gives us 3. So the left side becomes: 4 plus 3

Now, let's evaluate the right side of the equation: (4 plus 2) plus 1

The inner parentheses indicate that we should first add 4 and 2, which gives us 6. So the right side becomes: 6 plus 1

No matter how we group the numbers, the result is always the same:

4 plus (2 plus 1) = 4 plus 3 = 7

and

(4 plus 2) plus 1 = 6 plus 1 = 7

Therefore, the equation 4 plus (2 plus 1) equals (4 plus 2) plus 1 exemplifies the Associative Property of Addition.
