## Math Problem Solving Comparison ### Overview The image presents a series of math word problems, each followed by two different model outputs (62B and 540B) attempting to solve the problem. Each model output is labeled as either "Correct" or "Incorrect" along with a brief explanation of the error, if any. ### Components/Axes Each problem is presented in a separate cell. Each cell contains: 1. **Question:** The original math word problem. 2. **62B Model Output:** The solution provided by the 62B model, followed by a correctness assessment. 3. **540B Model Output:** The solution provided by the 540B model, followed by a correctness assessment. ### Detailed Analysis or ### Content Details **Problem 1:** * **Question:** Tracy used a piece of wire 4 feet long to support tomato plants in the garden. The wire was cut into pieces 6 inches long. How many pieces did she obtain? * **62B Model Output:** She cut the wire into 6 inch pieces. This means she got 4 * 6 = 24 pieces. The answer is 24. (Incorrect: semantic understanding error) * **540B Model Output:** The wire was 4 feet long. This means it was 4 * 12 = 48 inches long. It was cut into pieces 6 inches long. This means she obtained 48 / 6 = 8 pieces. The answer is 8. (Correct) **Problem 2:** * **Question:** Tom's ship can travel at 10 miles per hour. He is sailing from 1 to 4 PM. He then travels back at a rate of 6 mph. How long does it take him to get back? * **62B Model Output:** He travels from 1 to 4 PM. That means he travels for 3 hours. He travels back at 6 mph. That means he travels for 3 * 6 = 18 miles. The answer is 18. (Incorrect: semantic understanding error) * **540B Model Output:** He travels at 10 mph from 1 to 4 PM. This means he travels 3 hours. 3 hours at 10 mph means he travels 3 * 10 = 30 miles. He then travels back at 6 mph. This means he travels 6 miles per hour. He has to travel 30 miles, so it takes him 30 / 6 = 5 hours. The answer is 5. (Correct) **Problem 3:** * **Question:** Stephen placed an online order for groceries. His final bill came to $40.00. Because this was through a delivery vendor, they tacked on a 25% fee to his final total and charged him $3.00 in delivery fees. Stephen also added a $4.00 tip. After the extra fees, what was the final price of Stephen's groceries? * **62B Model Output:** The final price of Stephen's groceries was $40.00. The delivery vendor added 25% to the final total, so the final total was 125% of $40.00. This means the final total was 125% * $40.00 = $50.00. The delivery vendor also charged $3.00 in delivery fees. So the final price of Stephen's groceries was $50.00 + $3.00 = $53.00. The answer is $53.00. (Incorrect: one step missing error) * **540B Model Output:** Stephen's bill was $40.00. The delivery vendor added 25% to the bill. This means the bill was increased by 25% of $40.00. This is 0.25 * $40.00 = $10.00. The delivery fee was $3.00. The tip was $4.00. So the total bill was $40.00 + $10.00 + $3.00 + $4.00 = $57.00. The answer is 57. (Correct) **Problem 4:** * **Question:** There are four schools competing at a basketball tournament. Each school has sent a girls' basketball team and a boys' basketball team and each team has 5 players each. Each school has also sent a coach for each team. In total, how many people have all of the schools sent? * **62B Model Output:** There are 4 schools. Each school has sent a girls' basketball team and a boys' basketball team. Each team has 5 players each. That means there are 4 * 2 * 5 = 40 players. Each team has a coach. That means there are 40 + 4 = 44 coaches. The answer is 44. (Incorrect: one step missing error) * **540B Model Output:** Each school has sent 2 teams, each with 5 players. This means each school has sent 2 * 5 = 10 players. Each school has also sent 2 coaches. This means each school has sent 10 + 2 = 12 people. There are 4 schools, so in total all of the schools have sent 4 * 12 = 48 people. The answer is 48. (Correct) ### Key Observations * The 540B model consistently provides the correct answers for all four problems. * The 62B model makes errors in all four problems, indicating a potential weakness in its problem-solving approach. * The errors made by the 62B model are described as "semantic understanding error" or "one step missing error," suggesting difficulties in interpreting the problem's context or completing all necessary steps. ### Interpretation The data suggests that the 540B model is more reliable and accurate in solving math word problems compared to the 62B model. The 62B model's errors highlight the importance of semantic understanding and thoroughness in problem-solving. The comparison demonstrates the varying capabilities of different models in tackling similar tasks. The 540B model appears to have a more robust understanding of the underlying mathematical principles and is better equipped to translate word problems into accurate solutions.
