Calculate the Difference: Solving 3550 - 1050

Q: Why do I need to line up the numbers by place value?

Place value alignment ensures you're subtracting units from units, tens from tens, etc. Without proper alignment, you'll get the wrong answer because you're mixing different place values.

Q: How can I check if my subtraction is correct?

Use addition to check subtraction! Add your answer to the number you subtracted: $ 2500 + 1050 = 3550 $. If you get the original number, you're right!

Q: Should I start from the left or right when subtracting?

Always start from the rightmost column (units place) and work left. This ensures proper handling of any borrowing that might be needed in more complex problems.

Q: What does the answer 2500 represent?

The answer $ 2500 $ represents the difference between 3550 and 1050. It tells you how much larger 3550 is compared to 1050.

Step-by-step solution

To solve the problem of subtracting 1050 from 3550, we follow these steps:

Step 1: Identify the given information. We are given two numbers: 3550 and 1050.
Step 2: Set up the subtraction to find the difference.
Step 3: Perform the subtraction by aligning the numbers vertically and subtract each column starting from the right.

Common Mistakes

Avoid these frequent errors

Subtracting smaller from larger regardless of position
Don't subtract 1 from 3 in all columns just because 1 is smaller = wrong answer like 2450! This ignores place value completely and gives incorrect results. Always subtract the bottom number from the top number in each column, following proper place value alignment.
