How to remember multiplication tables upto 100?

As a student growing up in the school, I found it extremely hard to memorize the multiplication table. At times, it made me feel that I am really poor in mathematics. Later, I realized, I was not alone. Most of the students find it hard to memorize the multiplication table. In this tutorial, we will see how to remember multiplication tables upto 100. Later, we will see, how to use this learning to remember the multiplication table till 1000, or may be upto 10000.

With proper practice, you can remember the multiplication till 10000. Now, I would assume, you atleast know the multiplication table till 10 and can do basic addition mentally.

Let us say you want to recall the multiplication table of 41. If you look 41 as a single number, you may find it difficult. Instead separate 41 as 4 and 1.

Important : Notice the carry forward in the multiplication. Since we are separating the digits into single digits you need to keep only 1 digit and the rest of the digits are carry-forward.

In the previous example, we have considered probably the most easier multiplication table. You can easily replicate the multiplication table of numbers such as 31, 51, 81, 91 etc

Consider another example : Let us say we need to obtain the multiplication table of 76.
