Commutative Property of Addition

The commutative property of addition states that changing the order of addends does not change the sum. In other words, a + b = b + a.

Examples:

3 + 4 = 4 + 3

7 + 2 = 2 + 7

Visualization:

Illustration or diagram demonstrating the commutative property.

Real-life Example:

When arranging 3 books and 4 books on a shelf, the total number of books is the same whether you put the 3 books first and then the 4 books, or vice versa.

Practice Problems:

Solve the following: 5 + 6 = ?

Solve the following: 8 + 2 = ?
