Sid’s answer of 32 is correct.

Answer 1

To evaluate Sid's work, let's analyze the statements given based on the subtraction of 214 from 346:

1. Sid lined up the place values correctly.

   • If Sid correctly aligned the digits based on their place values (hundreds, tens, ones), then this statement is true.

2. Sid forgot to subtract the hundreds place, so his answer is incorrect.

   • If Sid did not correctly subtract the hundreds place (3 from 2, or resulting in a negative number), then this statement is true.

3. Sid should have written 214 on top and 346 on bottom.

   • The order of the numbers is crucial in subtraction. The larger number should be on top (346) and the smaller number (214) on the bottom, so this statement is true.

4. Sid’s answer of 32 is correct.

   • If the calculation of 346 - 214 does not yield 32 (it actually equals 132), then this statement is false.

Based on this analysis, the two true statements about Sid's work are:

• Sid lined up the place values correctly. (if he did)
• Sid should have written 214 on top and 346 on bottom.

If he forgot to consider the hundreds in the actual subtraction, where he may end up with an incorrect answer, then Sid forgot to subtract the hundreds place, so his answer is incorrect is also true.

Thus, the answers could likely be:

1. Sid should have written 214 on top and 346 on bottom.
2. Sid forgot to subtract the hundreds place, so his answer is incorrect.
