Subtraction of 5-Digit Numbers

We have learnt already subtraction of 4-digit numbers with regrouping. Subtraction of 5-digit numbers can also be done in the same way.

1. Subtract 28051 from 51278.

Solution:

Step I: Arrange the numbers vertically.

Step II: Subtract the ones. 8 - 1 = 7 ones. Write 7 in ones column.

Step III: Subtract the tens. 7 tens - 5 tens = 2 tens. Write 2 in tens column.

Step IV: Subtract the hundreds. 2 - 0 = 2 hundreds. Write 2 in hundreds column.

Step V: Subtract the thousands. Since 8 > 1, we cannot subtract. Regroup 5 ten thousands and 1 thousand. 5 ten thousands + 1 thousand = 4 ten thousands + 11 thousands. 11 - 8 = 3 thousands. Write 3 in thousands column.

Step VI: Subtract the ten thousands. 4 - 2 = 2 ten thousands. Write 2 in ten thousands column.
