Question Video: Multiplicative Identity Property Mathematics • Fourth Year of Primary School

Video Transcript

Beverley is working on memorizing her multiplication facts. She noticed that when she multiplies a number by one, she gets the same number she started with. What is the name of this property?

So if we would take any number, for example five, and we multiply it by one, we get an answer of five. So when you multiply it by one, you get the same number that you started with.

This is called the identity property. We can imagine it as, what can you multiply to a number that lets it keep its identity. That would be one. So if you take five and multiply it by one, its identity is kept, it is still a five. So again, what is the name of this property? It is called the identity property.
