How to Solve 12 x 9: Using Multiplication Table and Vertical Multiplication Method

12 X 9

108

To calculate 12 x 9, we can use the multiplication table or the vertical multiplication method.

Using the multiplication table:

We look for the row of the first factor (12) and the column of the second factor (9). The number at the intersection of the row and the column gives us the product.

| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
–|—|—|—|—|—|—|—|—|—|
1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
2 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 |
3 | 3 | 6 | 9 | 12 | 15 | 18 | 21 | 24 | 27 |
4 | 4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 |
5 | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 |
6 | 6 | 12 | 18 | 24 | 30 | 36 | 42 | 48 | 54 |
7 | 7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 |
8 | 8 | 16 | 24 | 32 | 40 | 48 | 56 | 64 | 72 |
9 | 9 | 18 | 27 | 36 | 45 | 54 | 63 | 72 | 81 |

In this case, we find 108 at the intersection of row 12 and column 9. Therefore, 12 x 9 = 108.

Using the vertical multiplication method:

We write the factors vertically and multiply the digits of the ones place, placing the result below the line. Then, we multiply the digits of the tens place, adding a 0 at the end, and place the result below the first result. Finally, we sum the two results to obtain the product.

1 2

——
18
10 8
——
10 8

Again, we get 108 as the product of 12 and 9.
