Problem: A butterfly collector managed to catch 13 beautiful butterflies one morning. If at the end of the day there are only 6 butterflies in his collection, how many butterflies flew away during the day?
DeepSeek Coder 33B:
Reasoning: The butterfly collector started with 6 butterflies. He caught 13 more butterflies. So, the total number of butterflies at the end of the day is 6 + 13 = <<6+13=19>>19. The number of butterflies that flew away during the day is the total number of butterflies at the end of the day minus the initial number of butterflies. 19 - 6 = <<19-6=13>>13 butterflies flew away during the day.

Problem: After a birthday party, you see one piece of cake left. If you originally had a whole cake that was cut into h slices, and each slice was equal in size, then how many slices were there in the whole cake, given that 12 pieces have been eaten during the party?
DeepSeek Coder 33B:
Reasoning: Let's denote the number of slices in the whole cake as h. The number of slices eaten during the party is 12. The number of slices left after the party is 1. So, we have the equation: h - 12 = 1. Solving this equation for h gives us h = 12 + 1 = 13. So, the original cake was cut into 13 slices.

Problem: A mountain climber starts at a point that is m feet high. After climbing downwards for a while, they reach a point that's 10 feet high. If they had climbed down 4 feet to reach this point, how high was the point where they started?
DeepSeek Coder 33B:
Reasoning: The climber started at a point that is m feet high. They climbed downwards for a while, reaching a point that's 10 feet high. If they had climbed down 4 feet to reach this point, then the point where they started is m + 4 feet high. Let's denote the height of the point where they started as m. The height of the point where they started is m + 4 feet high. The height of the point where they started is 10 feet high. Therefore, m = 10 - 4 = <<10-4=6>>6 feet. So, the point where they started was 6 feet high.

Problem: A fashion designer started with a total of a certain number of blue dresses. After selling 13 of them, there were only 2 left in stock. How many blue dresses did the designer start with?
DeepSeek Coder 33B:
Reasoning: If the designer started with a total of 'x' blue dresses, then after selling 13 of them, there were only 2 left in stock. This means that the designer started with 'x' - 13 + 2 = 'x' - 11 dresses. Hence, the designer started with 'x' - 11 = <<x-11>>x-11 dresses.

Problem: A desk drawer had 6 pens at the beginning of the day. At the end of the day, it acquired a total of 12 pens because some were dropped off in the drawer by office workers. How many pens did office workers drop off in the drawer throughout the day?
DeepSeek Coder 33B:
Reasoning: The total number of pens in the drawer at the end of the day is 6 (the initial number of pens) + 12 (the number of pens dropped off). Therefore, the number of pens dropped off in the drawer throughout the day is 12 (the total number of pens in the drawer at the end of the day) - 6 (the initial number of pens) = 12 - 6 = 6.
Expected answer: 6

Problem: A shape enthusiast begins with a collection of 15 different types of shapes. Later, she decides to give some away and is left with 11 types of shapes. How many different types of shapes did she give away?
DeepSeek Coder 33B:
Reasoning: The shape enthusiast started with 15 different types of shapes. After giving away some, she is left with 11 types of shapes. To find out how many types of shapes she gave away, we subtract the number of types she has left (11) from the total number she started with (15). 15 - 11 = <<15-11=4>>4 types of shapes were given away.

DeepSeek Coder 33B:
Reasoning: The total number of bikes at the end of the day is the sum of the initial number of bikes and the new bikes shipped. Therefore, the number of new bikes shipped is the total number of bikes at the end of the day minus the initial number of bikes. 14 - 4 = <<14-4=10>>10 bikes were shipped to the shop today.
Expected answer: 10
Correct? Yes
Problem: A child starts with 2 blue colored pencils, and then a classmate gives them some more. In the end, they have 3 blue colored pencils. How many colored pencils did their classmate give them?
DeepSeek Coder 33B:
Reasoning: The child started with 2 blue colored pencils. Then they received some more. In the end, they have 3 blue colored pencils. So, the difference between the number of pencils they started with and the number of pencils they have in the end is the number of pencils their classmate gave them. 2 (starting pencils) - 3 (final pencils) = -1 (classmate's pencils) However, the number of pencils cannot be negative. So, the classmate did not give them any pencils.

Problem: You start with 12 dollars in your wallet. By the end of a shopping trip, you find that you now have 16 dollars left in your wallet after receiving some change. How much money in dollars did you receive as change during the trip?
DeepSeek Coder 33B:
Reasoning: The total amount of money in your wallet before and after the shopping trip is 12 dollars. The difference between these two amounts is the amount of money you received as change. Change received = 12 - 16 = <<12-16=-4>>-4 dollars. However, the amount of money in your wallet cannot be negative. Therefore, the change received during the trip must be a positive number. Change received = 16 - 12 = <<16-12=4>>4 dollars.
