Trick to memorize 9th Table Easily...

In today’s post we are going to talk about multiplication tables. Normally kids are struggling in multiplication tables. Usually a dare and complex issue, because we have to memorize all the tables, sometimes using songs or rhymes helps to remember them more easily. 

When learning multiplication tables, the 9 table might be a little hard to master. However, some tricks we can use that help our kids to learn it easier. Some of the methods are :

1. Countdown method

2. Less than 1, Subtract from 9 method

3. Finger method

Let us see the Methods....

Method I : Countdown method

Method II : Less than 1, Subtract from 9 method (Or) Substitution Method

In this method, we are using pairs of 9. Using this substitution method we can instantly say the product of any multiplier by 9.  First digit should be one less than the multiplier, and the second digit will be arrived by Subtracting the first digit from 9.

Example : 

If we want to find 9 X 8. 

Here 8 is the multiplier. Hence the first digit will be one less than the multiplier (8-1=7) i.e 7, the second digit will be (9 - 7),  2. Thus we got the answer 9 x 8 = 72

Method III : Finger Method

This finger method will allow us to calculate the 9 table from 1 to 10. Multiplying 9 by any larger number can't be done using the finger trick method. It also can't be used to multiply by 9 by fractions or any other number that is not an integer.

1. Hold your hands up in front of you : Make sure that your fingers are pointing up, that your hands are next to one another, and that your palms are facing away from your body.  Our hands are the basis for calculating 9 table.

2. Assign your fingers a number by counting upwards from left to right 

3. Determine what number we need to multiply 9.

4. Fold down the finger that matches the number you want to multiply by 9 






  If we want to multiply 9x1, we have to fold down finger which is assigned to 1. Refer to the above picture 1 is assigned to left side.

If we multiply 9 x 2, we have to fold down the finger that is second from the left : Your left ring finger. When we multiply 9x6, we will fold down the finger in the "6" spot : Right thumb. 







5. Count the number of fingers that are to the left of the folded finger : For example, if we are solving the problem of 9 x 6, there should be 5 fingers (all the fingers on the left hand) standing up to the left of the folded sixth finger (right thumb). If we are solving the problem of 9x1, there should be zero fingers standing up to the left of the folded first finger.

6. Put the tens spot and the ones spot together to get the answer : By combining together the number of fingers to the left of the folded finger (tens place) and the number of fingers to right of the folded finger (ones place), we will get the final answer for that times of  9 table.

For example, if we want to solve 9x6, we will have 5 fingers to the left of the folded "6" finger and 4 fingers to the right of it. Then 5 is in the tens place and the 4 is in the ones place. Put it together to get 54, which is the correct answer.

If however, we are going to solve for 9x8, we will have 7 fingers to the left of the folded "8" finger (right middle finger) and 2 fingers to the right of it. The 7 is in the tens place and 2 is in the ones place. Putting it together we will get 72, which is the correct answer.

Cross-check the Product :

Nine table has the great trick that the digit sum of the product will always be 9. 

This works as follows:
     9 x 1 = 09  ==>  0 + 9 = 9
     9 x 2 = 18  ==>  1 + 8 = 9
     9 x 6 = 54  ==>  5 + 4 = 9 .... etc.,

Let us train your kids with these tricks that make learning multiplication tables a more dynamic and fun task. Make the younger minds a "Math Genius" !!!

Memorizing tables makes the future math work easier.
