when we subtract large numbers and the bottom number in the ones place is greater than the top number in the ones place,we must borrow 10ones from the
To borrow from the next place value, such as the tens place, when subtracting large numbers, follow these steps:
1. Start by writing down the larger number on top and the smaller number underneath it. Make sure to align the place values correctly.
For example, let's subtract 534 from 827:
827
- 534
2. Begin from the rightmost column (ones place) and compare the digit in the bottom number (4) with the digit in the top number (7). Since 7 is greater than 4, we need to borrow 10 ones from the tens place.
3. To borrow, reduce the digit in the tens place of the top number (2) by 1, making it 1, and add it to the ones place of the bottom number (4 + 10), making it 14. Write this new number below the original bottom number.
Here's the updated calculation:
827
- 534
-------
13
4. Now, subtract the digits column by column, starting from the right. In this case, subtract 4 from 14, which equals 10, and write down the result below the line.
827
- 534
-------
10
5. Move to the next column (the tens place) and subtract the digits there. Subtract 3 from 2. Since 2 is smaller than 3, we need to borrow again.
6. Repeat steps 2 and 3 for the tens place. Borrow 1 from the hundreds place, reducing the digit in the hundreds place of the top number (8) to 7, and add it to the tens place of the top number, making it 12. Write this new number below the top number.
Here's the updated calculation:
82
- 53
-------
10
7. Now, subtract the digits column by column, starting from the right. Subtract 3 from 12, resulting in 9, and write down the answer below the line.
82
- 53
-------
9
8. Finally, subtract the digits in the hundreds place. Subtract 5 from 7, resulting in 2, and write down the answer below the line.
82
- 53
-------
29
Therefore, when subtracting large numbers and the bottom number in the ones place is greater than the top number in the ones place, we need to borrow 10 ones from the next place value and continue the subtraction accordingly.
