Here we will find out 2-digit numbers subtraction utilizing brief kind.
Let’s attempt to fix the copying:
Subtraction of 2-Digit Numbers with Regrouping utilizing Short Form.
1. Deduct 49 from 75.
|
In the offered numbers, 75 is higher than 49. We compose 49 listed below 75 as revealed on the. Now we take the following actions. |
|
|
Step I: Subtract the ones: We can not deduct 9 ones from 5 ones. We obtain 1 10, from 7 10s leaving behind 6 10s. Now, we have 1 10 + 5 ones = 15 ones. 15 ones – 9 ones = 6 ones. Write 6 under ones column. Step II: Subtract the 10s: 6 10s – 4 10s = 2 10s. Write 2 under 10s column. |
Therefore, 75 – 49 = 26.
2. Deduct 28 from 47.
|
In the offered numbers, 47 is higher than 28. We compose 28 listed below 47 as revealed on the. Now we take the following actions. |
|
|
Step I: Subtract the ones: We can not deduct 8 ones from 7 ones. We obtain 1 10, from 4 10s leaving behind 3 10s. Now, we have 1 10 + 7 ones = 17 ones. 17 ones – 8 ones = 9 ones. Write 9 under ones column. Step II: Subtract the 10s: 3 10s – 2 10s = 1 10. Write 1 under 10s column. |
Therefore, 47 – 28 = 19
3. Deduct 39 from 90.
|
In the offered numbers, 90 is higher than 39. We compose 39 listed below 90 as revealed on the. Now we take the following actions. |
|
|
Step I: Subtract the ones: We can not deduct 9 ones from 0 ones. We obtain 1 10, from 9 10s leaving behind 8 10s. Now, we have 1 10 + 0 ones = 10 ones. 10 ones – 9 ones = 1 one. Write 1 under ones column. Step II: Subtract the 10s: 8 10s – 3 10s = 5 10s. Write 5 under 10s column. |
Therefore, 90 – 39 = 51.
