We will learn subtracting 4-digit, 5-digit and 6-digit numbers without
regrouping.
We first arrange the numbers one below the other in place value columns and then subtract the digits under each column as shown in the following examples.
Solved Examples on Subtraction of 4-Digit Numbers without Regrouping:
1. Subtract 3248 from 6589.
Solution:
Step I: Arrange the numbers vertically. Step II: Subtract ones. 9 – 8 = 1 one. Write 1 in ones column. Step III: Subtract the tens. 8 – 4 = 4 tens.. Write 4 in tens column. Step IV: Subtract the hundreds. 5 – 2 = 3 hundreds. Write 3 in hundreds column. Step V: Subtract the thousands. 6 – 3 = 3 thousands. Write 3 in thousands column. |
Thus, 6589 – 3248 = 3341. |
2. Subtract 3711 from 9911.
Solution:
Step I: Arrange the numbers vertically. Step II: Subtract ones. 1 – 1 = 0 one. Write 0 in ones column. Step III: Subtract the tens. 1 – 1 = 0 tens.. Write 0 in tens column. Step IV: Subtract the hundreds. 9 – 7 = 2 hundreds. Write 2 in hundreds column. Step V: Subtract the thousands. 9 – 3 = 6 thousands. Write 6 in thousands column. |
Thus, 9911 – 3711 = 6200. |
Solved Examples on Subtraction of 5-Digit Numbers without Regrouping:
1. Subtract 54231 from 86954.
Solution:
Step I: Subtract ones. 4 – 1 = 3. Write 3 under ones. Step II: Subtract tens. 5 – 3 = 2. Write 2 under tens. Step III: Subtract hundreds. 9 – 2 = 7. Write 7 under hundreds. Step IV: Subtract thousands. 6 – 4 = 2. Write 2 under thousands. Step V: Subtract ten thousands. 8 – 5 = 3. Write 3 under ten thousands. Therefore, the difference is 32723 |
Solved Examples on Subtraction of 6-Digit Numbers without Regrouping:
1. Subtract 134108 from 275638
Solution:
Step I: Subtract ones. 8 – 8 = 0. Write 0 under ones. Step II: Subtract tens. 3 – 0 = 3. Write 3 under tens. Step III: Subtract hundreds. 6 – 1 = 5. Write 5 under hundreds. Step IV: Subtract thousands. 5 – 4 = 1. Write 1 under thousands. Step V: Subtract ten thousands. 7 – 3 = 4. Write 4 under ten thousands. Step VI: Subtract lakhs. 2 – 1 = 1. Write 1 under lakhs. Therefore, the difference is 141530 |
