In this lesson we'll take a look at the properties of real numbers. Some of these properties involve commutative, associative, distributive, identity, inverse, and zero properties. The commutative property of addition and multiplication says that the order of addition or multiplication does not matter. For example, 2+3 is as same as 3+2. Also, 2x3 is as same as 3x2. You'll also learn about the other properties and see the examples of each. You'll see what happens when you add zero or multiply by one, and you'll learn how these two are similar. When 0 is divided by a number, the result is always 0. However, it is a bit tricky when it comes to dividing a number by 0.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
