Which property is illustrated by the statement

7+ (3+1) = 7 + (1+3)

The property that is illustrated by the statement is the commutative property of addition.

The property illustrated by the given statement is the commutative property of addition.

The property illustrated by the statement 7 + (3 + 1) = 7 + (1 + 3) is the Commutative Property of Addition.

To understand and apply the Commutative Property of Addition, we need to know that it states that the order of the numbers being added does not affect their sum. In other words, when we add two or more numbers, we can change the order in which we add them, and the result will remain the same.

Let's break down the expression 7 + (3 + 1) step by step:
- First, we add 3 and 1, which gives us 4.
- Then, we add 7 and 4, which gives us 11.

Now, let's look at the expression 7 + (1 + 3):
- First, we add 1 and 3, which gives us 4.
- Then, we add 7 and 4, which also gives us 11.

As you can see, the result is the same when we add the numbers in different orders. This demonstrates the Commutative Property of Addition.
