I think it depends on the definition of prime numbers your teacher chose. I choose the definition that they are natural numbers greater than 1 and are only divisible by 1 and itself. For example: 13 since 13 and 1 are it's only factors

So do you think you can now list the prime numbers between 1 and 10 (not including 10 since it doesn't say equal to)?

A math teacher is preparing an exam each of his Algebra class. Mathalino and Mathmatalino, covering topics A (circles) and B (inequalities). He wants to design the exams so that both classes will have the same number of questions on A and also on B. Each question on A is worth 15 points in section Mathalino and 20 points in section Mathmatalino while each question on B is worth 10 points in section Mathalino and 5 points in section Mathmatalino. If the total number of points in both exams is 100, how many questions should he ask on each topic?
