Question Video: Identifying the Properties of Multiplication in a Set of Numbers Mathematics • First Year of Preparatory School

Video Transcript

What property of multiplication is used in the sum four times one equals four?

Here we have the product of the number four and one. And we see that the result is actually equal to the first number. It’s equal to four. So what’s the name of this? Well, this is the multiplicative identity property. This property tells us that the product of any rational number and one is that rational number. Here, four is the rational number, and we’re left with four when we multiply it by one.
