Problem: There are originally 97 dinosaurs in a natural history museum's exhibit. However, the curator decides to add 'k' more of these prehistoric creatures to the exhibit. The total number of dinosaurs in the exhibit now reaches 98. Can you find out how many new dinosaurs the curator added?
Gemini-1.5 Pro:
Reasoning: To find out how many dinosaurs the curator added (represented by 'k'), we need to figure out the difference between the original number of dinosaurs and the new total. This can be represented by the equation: 97 + k = 98 To isolate 'k', we subtract 97 from both sides of the equation: 97 + k - 97 = 98 - 97 This simplifies to k = 1 ### Answer: 1

Problem: Lily has a number of dolls. If she were to donate 5 of her dolls, she would have 52 left. How many dolls does Lily have in total?
Gemini-1.5 Pro:
Reasoning: Let 'x' be the total number of dolls Lily has. After donating 5, she has x - 5 dolls left. We know this amount is equal to 52. So, we have the equation x - 5 = 52. To solve for x, we add 5 to both sides of the equation: x - 5 + 5 = 52 + 5. This simplifies to x = 57. ### Answer: 57
Expected answer: 57

Problem: The zoo started the day with some number of animals, which we'll call s. During the day, 24 animals were moved to a separate area of the zoo for cleaning and care. After this, there were still 75 animals visible to visitors in the main section of the zoo. How many animals were there in total at the zoo at the start of the day?
Gemini-1.5 Pro:
Reasoning: Since 24 animals were removed from the initial number, *s*, and 75 remained, we can set up the equation: s - 24 = 75. To find *s*, the initial number of animals, we add 24 to both sides of the equation: s - 24 + 24 = 75 + 24, giving us s = 75 + 24. Therefore, s = 99. ### Answer: 99
