Most of us have heard of the commutative property in math, though many of us aren’t sure what it actually means or why it’s so important. In very simple terms, the commutative property states that it doesn’t matter how you arrange numbers or other elements when doing addition and multiplication-they will always come out the same way. For example, in the equation 2 + 4 = 6, both 2 + 4 and 4 + 2 will always equal the same answer of 6, no matter which number you start with first in addition problems.

**What is the commutative property?**

The commutative property is a mathematical rule that states that when two numbers are multiplied together, the order of the numbers does not affect the answer. In other words, a x b = b x a. The commutative property is used in many countries, including the United States. It is often used when solving math problems involving addition and multiplication. For example, if you were to add 7 + 3, it would not matter if you added 3 + 7 first; you would still get 10 as your answer. The same goes for multiplication; 8 x 4 is the same as 4 x 8. The commutative property can be applied to more than just addition and multiplication; it also works with subtraction and division.

**What does it mean for multiplication to be commutative**

In mathematics, the commutative property is a property of some binary operations that states that the order of operands does not affect the result of the operation. In other words, for addition and multiplication, a + b = b + a and a × b = b × a. For subtraction and division, however, the reverse is true: a – b ≠ b – a and a ÷ b ≠ b ÷ a.

The commutative property can be illustrated by a simple example of addition. For example, to sum 2 + 3, we could have chosen one of two orders: (1) add 3 to 2 or (2) add 2 to 3. In both cases, we’d get 5. As another example, let’s examine what happens when we try to multiply two numbers together and swap their order: 5 × 7 = 35 and 7 × 5 = 35. When you compare these two products side-by-side, it becomes clear that multiplication is commutative for any numbers except 0 and 1.

**What does it mean for addition to be commutative**

In mathematics, the commutative property is a property of addition and multiplication, that states that for two numbers, the order does not matter. So, for example, 3 + 7 = 7 + 3. The same can be said for multiplication: 2 x 5 = 5 x 2.

Unlike multiplication, though, addition is not always commutative. For example, consider 6 + 4 and then 4 + 6. The two numbers are different. So what does it mean when addition is not commutative? Let’s say that you and a friend each owe $100 to another friend for a total debt of $200. You each pay your share of $100, so now you both owe your first friend $50. But when you pay back your debt, would you expect to give your friend $50 or would he expect you to give him $150? Addition is not commutative because even though 6 + 4 = 10 and 10 + 6 = 16, those two numbers don’t equal 16!

**Examples of Commutativity**

Commutativity is a property of mathematical operations that states that the order of operands does not affect the result. In other words, for addition and multiplication, a+b=b+a and a⋅b=b⋅a. The commutative property is not used in subtraction or division. For example, 3-5≠5-3.

You may remember learning about commutativity at school. One of your teachers or textbooks may have demonstrated how, for example, 3+5=8 and 5+3=8. That’s two examples of commutativity at work! The commutative property is one that is taught to every schoolchild so they can manipulate basic arithmetic with ease. Some students even learn it on their own before they get to high school as a means of simplifying working out problems mentally.

**Rules of Composition Involving the Commutative Property**

Here in the United States, we don’t generally use the commutative property when composing numbers. In mathematical terms, this would mean that when two numbers are added or multiplied together, it doesn’t matter what order they’re added or multiplied in. So, for example, 2 + 3 would be the same as 3 + 2. However, we usually just add and multiply numbers in the order they appear.
