Some Tricks to Make Times Tables Shorter
In today’s post we’re going to review our times tables, while at the same time learning a trick to make them shorter.
Before we start, you can review the times tables if you need to by clicking this link.
Are you ready? Let’s start!
Have you noticed that the numbers repeat across all the times tables?
For example, the 1 times table contains 1 x 2, which is the same as 2 x 1, and this appears in the 2 times table. If we already know that 1 x 2 = 2, we don’t need to learn that 2 x 1 = 2 because we already know it!
This happens because of the commutative property of multiplication: the order of the factors doesn’t change the result of the product. You can read about the properties of multiplication in this post if you don’t remember!
So, today we’re going to look at short times tables, removing all the multiplications that repeat and, therefore, the ones we don’t need to learn:
As you can see, there are fewer multiplications to learn than it seems… In this table you can find any of the complete times tables, look:
