To solve the subtraction problem , follow these steps:
Write down the numbers with their digits aligned according to place value:
Subtract each pair of digits starting from the right (units place):
Units place:
Tens place:
Hundreds place:
Thousands place: – since is less than , we need to borrow.
Borrows and adjusts:
Borrow from the ten-thousands place. Convert to , and increase thousands by : (because of borrowed 1 from ten-thousands).
Perform the borrowing adjustment and subtraction:
Thousands place after borrowing:
Ten-thousands place (after borrowing):
After performing these operations, the final result is:
Therefore, the difference when is subtracted from is:
2000
\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
You need to borrow from the next place value! In this problem, borrow 1 from the ten-thousands place (making it 0) and add 10 to the thousands place (making it 10). Now you can subtract: 10 - 8 = 2.
Borrowing is like trading money! One ten-thousand is worth 10 thousands, just like one dollar is worth 10 dimes. When you borrow 1 from ten-thousands, you get 10 extra thousands to work with.
Use addition to check! Add your answer (2000) to the number you subtracted (8154). If you get the original number (10154), your answer is right!
That makes it easier! When digits are the same (like 4-4, 5-5, 1-1), the result is always 0. Focus your attention on the places where digits are different.
Yes, always start from the rightmost column (ones place) and work left! This ensures you handle any borrowing correctly as you move through each place value.
