Commutative Property Of Addition

The subject of commutative property of addition encompasses a wide range of important elements. Properties of addition (article) | Khan Academy. The commutative property of addition tells us that it doesn't matter if the 0 comes before or after the number. Here's an example of the identity property of addition with the 0 after the number: Commutative law of addition (video) | Khan Academy.

Additionally, so no matter how you do it and no matter what order you do it in-- and that's the commutative law of addition. It sounds very fancy, but it just means that order doesn't matter if you're adding a bunch of things. Now, the associative law of addition tells us it doesn't matter whether we add 77 and 2 first or whether we add 2 and 3 first. We can associate them differently.

Building on this, associative and commutative properties of addition with negatives. For example, we know that nine plus seven is equal to 16, and if I just change the order the commutative property tells us, well, seven plus nine, it applies to addition. If I swap the order here it's still going to be equal to 16, but that's not true if I do nine minus seven or seven minus nine. Now, this commutative law of addition sounds like a very fancy thing, but all it means is if you're just adding a bunch of numbers, it doesn't matter what order you add the numbers in. Additionally, commutative property of addition: A + B = B + A This property states that you can add two matrices in any order and get the same result.

This parallels the commutative property of addition for real numbers. For example, 3 + 5 = 5 + 3 . The following example illustrates this matrix property. Commutative property of rational numbers (video) | Khan Academy.

Join us as we explore the commutative property and how it applies to different operations with rational numbers. Through clear examples, we demonstrate whether addition, subtraction, multiplication, and division of rational numbers are commutative or not. Commutative property of multiplication (video) | Khan Academy. It's a fancy word but it's really just saying that whether you're doing six times four or four times six the commutative property of multiplication says, "Hey, those two things "are going to be equivalent."
