Let's solve using the vertical subtraction method:
Step 1: Write the numbers in column form, ensuring they are aligned by place value:
Step 2: Subtract each digit starting from the right (units place). First, inspect the units place:
We need to subtract 3 from 2. Since 3 > 2, we must borrow.
Borrow 1 from 600 (next higher order, thousands in this case):
The result: Change 6002 to 5992.
Now, subtract , in the units place.
Step 3: Move to the tens place:
Subtract .
Step 4: Move to the hundreds place:
Subtract .
Step 5: Move to the thousands place:
We have 5 remaining and no subtraction needed here.
Therefore, the result is .
Therefore, the solution to is .

\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
When you have zeros in the middle, you must borrow through all of them! The 6 in 6002 becomes 5, and each 0 becomes 9 until you reach the column where you actually need the extra 10.
Always borrow from the column to the left (the next higher place value). You can't borrow from smaller place values because they represent smaller amounts.
It becomes 5992! The 6 becomes 5, both 0s become 9s, and the final 2 becomes 12 (which you write as 2 but think of as 12 for subtraction).
No, always work from right to left in subtraction! Starting from the left can lead to borrowing mistakes because you might change digits you haven't processed yet.
Use addition to check: . If your addition gives you the original larger number, your subtraction is correct!
Don't panic! Start over with the borrowing step. Write down each step clearly: 6002 → 5992, then subtract column by column. Practice makes perfect!
