Let's analyze Sid's work step by step:
-
Line Up Place Values: Sid lined up the numbers vertically, putting 346 on top and 214 underneath. This part is correct, as he correctly aligned the hundreds, tens, and units.
-
Subtracting Hundreds Place: Sid should have subtracted 200 (the hundreds in 214) from 300 (the hundreds in 346). He appears to have neglected this step, as 346 - 214 is not 32. If he had subtracted the hundreds correctly, he would have needed to calculate:
- 300 - 200 = 100 (hundreds)
- 40 - 10 = 30 (tens)
- 6 - 4 = 2 (units)
- Combine these: 100 + 30 + 2 = 118.
-
Correctness of the Answer: Since the resulting answer of 32 is inaccurate, it proves Sid did not perform the subtraction correctly.
-
Position of Numbers: In subtraction, typically, the larger number (minuend) is written on top, which Sid did correctly.
Based on this analysis, the two correct statements would be:
- Sid lined up the place values correctly.
- Sid forgot to subtract the hundreds place, so his answer is incorrect.
So, the selected statements would be:
- Sid lined up the place values correctly.
- Sid forgot to subtract the hundreds place, so his answer is incorrect.
