What are the errors in Sid's calculation of 346 minus 214, and which statements accurately describe his work?

Answer 1

To assess Sid's calculation of \( 346 - 214 \), we should first compute the correct answer.

Calculating the subtraction manually:

1. Subtract the ones place: \( 6 - 4 = 2 \)
2. Subtract the tens place: \( 4 - 1 = 3 \)
3. Subtract the hundreds place: \( 3 - 2 = 1 \)

So, \( 346 - 214 \) equals \( 132 \).

Now, let's consider Sid's potential errors and the statements that may be accurate based on his work. Common issues in subtraction that may happen include:

• Incorrect borrowing when the top digit is smaller than the bottom digit.
• Mistakes in alignment of the numbers vertically.
• Simple arithmetic errors in subtracting digits.

Without Sid's specific calculations, we can only generically describe potential mistakes. For example:

Errors Sid could make might include:

• Miscalculating the tens or hundreds place.
• Failing to borrow correctly when needed.

Statements that could accurately describe his work could be:

1. He miscalculated one or more of the digits.
2. He might have made a borrowing mistake.

If you provide specific details about Sid's calculations, I can help identify the exact errors and assess which statements accurately describe his work.
