Tricks to Memorise Table of 9
Memorizing the multiplication table for 9 can be made easier with a few tricks. Here are some techniques to help you remember the table of 9:
Finger Trick
Hold both hands in front of you with your fingers spread out. To find the product of 9 and a number, let’s say 2, fold down the 2nd finger. The number of fingers to the left represents the tens digit, and the number of fingers to the right represents the ones digit.
In this case, you have 1 finger to the left and 8 fingers to the right, so the product is 18.
Pattern Recognition
Observe the pattern in the multiples of 9. Notice that the tens digit increases by 1 from right to left, and the ones digit decreases by 1 from left to right. For example:
|
9 × 1 |
= |
09 |
|
9 × 2 |
= |
18 |
|
9 × 3 |
= |
27 |
|
9 × 4 |
= |
36 |
|
9 × 5 |
= |
45 |
|
9 × 6 |
= |
54 |
|
9 × 7 |
= |
63 |
|
9 × 8 |
= |
72 |
|
9 × 9 |
= |
81 |
|
9 × 10 |
= |
90 |
In the above table, we can observe the pattern of the tens place increases by 1 each time (0, 1, 2, 3, …), and the ones place decreases by 1 each time (9, 8, 7, 6, …)
Replacing 9 with 10 and then Subtract the Multiplier
If you want to learn the table of 9 by replacing 9 with 10 and then subtracting the multiplier, here’s how you can do it:
Start with the Table of 10: Begin by writing down the table of 10.
|
Number |
Product (10 times Number) |
|---|---|
|
1 |
10 × 1 = 10 |
|
2 |
10 × 2 = 20 |
|
3 |
10 × 3 = 30 |
|
4 |
10 × 4 = 40 |
|
5 |
10 × 5 = 50 |
|
6 |
10 × 6 = 60 |
|
7 |
10 × 7 = 70 |
|
8 |
10 × 8 = 80 |
|
9 |
10 × 9 = 90 |
|
10 |
10 × 10 = 100 |
Subtract the Multiplier: For each product in the table of 10, subtract the multiplier to get the corresponding product in the table of 9.
|
Number |
Product (10 times Number) – multiplier |
9 times Number |
|---|---|---|
|
1 |
10 – 1 |
9 |
|
2 |
20 – 2 |
18 |
|
3 |
30 – 3 |
27 |
|
4 |
40 – 4 |
36 |
|
5 |
50 – 5 |
45 |
|
6 |
60 – 6 |
54 |
|
7 |
70 – 7 |
63 |
|
8 |
80 – 8 |
72 |
|
9 |
90 – 9 |
81 |
|
10 |
100 – 10 |
90 |
From the above tricks you can easily master the table of 9.
