Large numbers can be multiplied on paper using a method called long multiplication. It functions similarly to regular on-paper multiplication, but is a little bit more complex as it involves two numbers with two or more digits. Below are the steps to go through, using an example
1. Set out the numbers as shown below.
12
x11
------
2. Multiply the first digit of the bottom number by the top number.
12
x11
------
12
3. Underneath this number, place a zero.
12
x11
------
12
0
4. Multiply the second digit of the bottom number by the top number, placing your answer after the zero.
12
x11
------
12
120
5. Add the products together to obtain your final answer.
12
x11
------
12
120
------
132
When dealing with numbers with more digits, an additional zero will need to be added. For example, when multiplying by the third digit of the bottom number, two zeros are to be added before the product.
