Subtract 951 from 1000: Vertical Subtraction Practice

To solve this problem, we'll follow these steps:

• Step 1: Set up the vertical subtraction with 1000 above 951.
• Step 2: Start subtracting from the rightmost digit.
• Step 3: Borrow as needed across zeros.
• Step 4: Perform the subtraction of each digit, ensuring proper arithmetic adjustment from borrowing.

Now, let's work through each step:
Step 1: We write $1000$ and $951$ in vertical alignment for subtraction.
Step 2: Begin from the units column: We need to subtract $1$ from $0$, so borrowing is required.
Step 3: As there are zeros in both the units and the tens place, we must borrow from the hundreds place and subsequently from the thousands place.
Step 4: Change $1000$ as follows for borrowing: The thousands digit gives 1 to the hundreds, transforming so it looks like $10$ at hundreds, zero at the thousands, from which the hundreds gives 1 to the tens, and similarly tens gives 1 to the units.
The number $1000$ effectively becomes $0990$ temporarily while processing subtraction:
- Now units column: $10 - 1 = 9$.
- In the tens column: $9 - 5 = 4$.
- In the hundreds column: $9 - 9 = 0$.
- Thousands column: $0 - 0 = 0$.

Therefore, the solution to the subtraction problem of $1000 - 951$ is $49$.
