Lesson 1: Multiplication as equal groups

Let's explore the idea of multiplication being the same as repeated addition. It shows how to express multiplication problems using repeated addition and highlights that multiplication is commutative, meaning the order of the numbers doesn't change the outcome.

• At , Sal was saying that "you can view multiplication as repeated addition." so is multiplication just reapeated addition?
• Multiplication, in a way, can be viewed as repeated addition. It's basically the exact same thing, but since repeated addition would take a lot longer, multiplication is much easier to do and remember. In short, yes, it is basically repeated addition.

• You can think of multiplication as just groups of another number. For instance, if there were 2 groups of 6 apples, there would be 12 apples. Instead of thinking 2x6=12, if that is hard for you, 6+6=12 is another thing you can do.

By the way, with this equation, you can also do 2+2+2+2+2+2=12 instead of 6+6=12, because they are equal.

• do you have to use addition for multiplication?
• Even though multiplication is addition, it doesn't mean that you have to use it when doing a multiplication problem. There are other ways of doing multiplication, and addition is just one of those many ways.

Some other ways might be:
- Memorizing your 1-12 times tables
- Algorithm
- Place Value
