Subtraction without Regrouping
Subtraction without regrouping:
We will learn subtracting 4digit 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 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.
