The question listed in paper (they modified 20 out of thousands in MATH dataset) as example is very far in calculating complexity from what I quoted in my comment above. Their question for your convenience: At each basketball practice last week, Jenny made twice as many free throws as she made at the previous practice. At her fifth practice she made 48 free throws. How many free throws did she make at the first practice?
