Multiplication as Repeated Addition

Multiplication is the continuous addition of same number to some extent.
So we can say multiplication as quickest addition (repeated addition).
For example, by adding 2 for 4 times we will get 8, 2 + 2 + 2 + 2 = 8.
Directly multiplying 2 with 4 also we can get 8. 4
× 2 = 8.
Hence, we can define the multiplication as repeated addition.
