0Lattice Method:
In Mathematics, the topic multiplication has many methods. One of it is Lattice method.
Practice Sum 1:
- 21 × 6
- Steps to multiply:
- The number 21 is formed by mixture of two numbers i.e. 20 + 1.
So, we can form a table as:
| × | 20 | 1 |
| 6 | 120 | 6 |
- Now, we have to multiply 6 × 20
- Answer is 120.
- Now, we have to multiply 6 × 1
- Answer is 6.
- Now we have to add the two boxes of the product that we have got.
- In other words we have to add the boxes having numbers 120 and 6.
- So, 120 + 6 = 126.
- So, our answer is 126.
- Therefore, 21 × 6 = 126.
Practice Sum 2:
- 45 × 12
- Now here, we have to follow the same procedure but twice.
- The number 45 is formed from two numbers i.e. 40 + 5.
- And the number 12 is formed by 10 + 2.
So we can make a table and solve the sum:
| × | 40 | 5 |
| 10 | 400 | 50 |
| 12 | 480 | 60 |
- Multiply 10 by 40 and 5.
- Again multiply 12 by 40 and 5.
- So we get the product in the remaining 4 boxes.
- So add the 4 boxes i.e. add 400 + 480 + 50 + 60.
- We get the final answer as 990.
