To solve the math problem (81,000 - 55,456) manually without a calculator, you can follow these steps:
Step 1: Start by aligning the numbers vertically, with the place values lined up.
81,000
- 55,456
Step 2: Begin subtracting from the rightmost place value, which is the ones place.
Since 0 is less than 6, we need to borrow from the tens place.
81,000
- 55,456
-------
Step 3: Borrowing from the tens place:
- Change the 8 into 7 in the tens place.
- Add 10 to the ones place (initially 0) to make it 10.
71,010
- 55,456
-------
Step 4: Now subtract, starting from the ones place.
- Subtract 6 from 10, which equals 4.
- Move to the tens place and subtract 5 from 5, which equals 0.
- Lastly, subtract 5 from 7, which equals 2.
71,010
- 55,456
-------
15,554
Step 5: The answer to the math problem (81,000 - 55,456) is 15,554.
Remember, when subtracting manually, it is crucial to align the numbers in their respective place values and work from right to left, borrowing when necessary.
