The Tricks Of Multiplication

Math will be easier if students develop their memory skills. Multiplication in mathematics is a fundamental operation, and, for sure, this operation is going to be used even in adulthood. We use multiplication in order to convert monetary currency from one country to another, we use it in order to approximate our monthly wage, and we use it in order to figure out how much the utility bills will be at the end of the month. So, knowing how to multiply two or more values is a must. Let’s see how we can make this easier.  

How To Learn The Multiplication Table Faster

The multiplication table can only be memorized. There is no other way to remember it. In school, students either learn the multiplication table as a song or as a mnemonic exercise. Even so, for some children telling stories in order to remember multiplication might be too overwhelming. There is a simpler way. 

 

  • Twinned multiplication  – 3 x 6 = 18, that means that 6 x 3 is also 18. 

Let’s try it:

 

1 x 2 = ?         2 x 1 = ?

 

2 x 2 = ?         

 

3 x 2 = ?         2 x 3 = ?

 

4 x 2 = ?         2 x 4 = ?

 

 … Keep on going on your own! 

 

  • Add the number to itself – 2 x 9 means 2 plus 2 by 9 times ( 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 18),

    so 2 x 9 = 18

 

At the same time, 9 x 2, also equals 18, because it’s 9 added 2 times, so 9 + 9 = 18. 

 

Give it a try:

 

3 x 2 = ( 3 + 3) = 

 

3 x 3 = ( 3 + 3 + 3) = 

3 x 4 = ( 3 + 3 + 3 + 3) = 

…Go on! How much is 3 added 10 times ( 3 x 10)? 

 

  • Whenever we multiply 6 by an even number, the product will end up with that even number:

 

Let’s try this: 6 x 2 = 12

 

        6 x 4 = 24

 

Multiply 6 by all even numbers and let’s test this theory: 

 

        6 x 6 = ? 

                     6 x 8 = ? 

                   6 x 10 = ?

      6 x 12 = ?

                   6 x 24 = ?


  • Multiplying by 10, it’s just about adding the 0,  whenever we multiply a number by 10, we just need to put a 0 to that number.

For example, 2 x 10 equals 20. It’s the same for all numbers:

 

1 x 10 = ?

3 x 10 = ?

4 x 10 = ?

5 x 10 = ?

6 x 10 = ?

12 x 10 = ?


  • Multiplying an even number will always result in an even number. When we multiply an even number by another even number, the product is an even number. When we multiply an even number with an odd number, the result is…an even number. Check out the multiplication table, and choose two numbers randomly. 

4 x 8 = 32 – an even number

 

5 x 6 = 30 – an even number. 

 

Try this rule several times and test the theories above for yourself!
