# Subtract the following numbers.           2 , 000 , 077         −           87 , 801 _

To determine

To calculate: The difference,

2,000,077      87,801_

Explanation

Given information:

2,000,077      87,801_

Formula used:

Steps for subtracting whole number,

Step 1: Line up the place values by writing the whole numbers in columns - units, tens, hundreds, thousands, and so on.

Step 2: Starting from the right with the units column, subtract the digits in each column.

Step 3: A digit must be borrowed from the column to the left of the working column, if the column cannot be subtracted.

Calculation:

To subtract the given numbers, align the numbers as,

2,000,077      87,801_

Subtract 1 from 7 in the units column.

71=6

Write 6 under the units column.

2,000,077      87,801_                 6

Subtract 0 from 7 in the tens column.

70=7

Write 7 under the tens column.

2,000,077      87,801_                76

In hundreds column 8 cannot be subtracted from 0, borrow 10 from the thousands column.

Subtract 8 from 10 in hundreds column.

108=2

Write 2 under the hundreds column.

2,000,077      87,801_              276
