When adding numbers, the order doesn't change the final sum! This is called the commutative property of addition. For example, $3 + 5$ is the same as $5 + 3$. It works no matter how many numbers you're adding! So, whether you add $2 + 4 + 6$ or $6 + 4 + 2$, the answer will always be $12$. Knowing this can make solving problems much easier and faster! 🧮
Match the term to its definition:
| Term | Definition |
|---|---|
| 1. Commutative Property | A. The result of adding two or more numbers |
| 2. Sum | B. Changing the order of addends does not change the sum |
| 3. Addend | C. A number being added |
| 4. Order | D. An arrangement or sequence of things. |
| 5. Equation | E. A mathematical statement that two expressions are equal. |
Match the correct term and definition. (Example: 1-B)
The _______ property of addition states that changing the _______ of addends does not change the _______. For example, $7 + 2$ is the same as $2 + _______. In both cases, the sum is _______.
