Methods to Calculate 3 x 13

There are several methods you can use to calculate 3 x 13. Understanding these methods can help you choose the one that suits you best.

Method 1: Repeated Addition

As mentioned earlier, multiplication can be viewed as repeated addition. To calculate 3 x 13 using this method, simply add 13 to itself three times:

13 + 13 + 13 = 39

This method is straightforward and effective, especially when you're first learning multiplication.

Method 2: Breaking Down Numbers

This method involves breaking down one of the numbers into smaller, more manageable parts. For instance, you can break 13 into 10 + 3. Then, multiply 3 by each part and add the results:

• 3 x 10 = 30
• 3 x 3 = 9
• 30 + 9 = 39

This method is useful for mental calculations and helps in understanding the distributive property of multiplication.

Method 3: Using a Multiplication Table

A multiplication table is an excellent tool for quick calculations. Locate the row for 3 and the column for 13. The intersection of this row and column will give you the answer, which is 39.
