To solve this subtraction problem of , we'll use vertical subtraction with borrowing:
Let's lay out the subtraction:
Follow these steps:
Step 1: Start with the ones column. Subtract 4 from 8. Since 8 is larger, we simply do .
Step 2: Move to the tens column. Subtract 7 from 6. Here, 6 is smaller than 7, so we need to borrow from the hundreds column.
- Cross out the "7" in hundreds place and reduce it by 1 to make it "6".
- Change 6 in the tens place to 16.
- Now, perform the subtraction: .
Step 3: Move to the hundreds column. Subtract 0 from 7 (after reduction): .
Thus, the result of the subtraction is:
Therefore, the answer to the subtraction problem is .

\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
In basic subtraction, we don't use negative numbers! When the top digit is smaller, you must borrow from the next column to make it larger. This keeps all digits positive.
Always borrow from left to right (higher place values to lower). Take 1 from hundreds, give 10 to tens. Think: "Big brother helps little brother!"
You'll need to borrow from the next non-zero digit first! For example, in 300 - 74, borrow from hundreds to make tens = 10, then borrow from tens to make ones = 10.
Add your answer back to what you subtracted: . If you get the original number (768), your borrowing was perfect!
Work column by column from right to left. Don't rush! Cross out and rewrite the new numbers clearly after each borrow so you don't get confused.
