Repeated multiplication can be used to find the area of a rectangle, the volume of a cube, and many other things. It is a fundamental operation in mathematics, and it is important to understand how to do it correctly.
To multiply two numbers using repeated multiplication, follow these steps:
1. Write down the first number.
2. Add the first number to itself as many times as indicated by the second number.
3. The final result is the product of the two numbers.
Here is an example of how to multiply 5 by 3 using repeated multiplication:
```
5 x 3 = 5 + 5 + 5
10 + 5
15
```
Therefore, 5 x 3 = 15.
