This puzzle is an interesting one and it requires some mathematical thinking to solve it. Let's break it down step by step.

Firstly, we have six 3's which we can use to make the number 31. We are also given the four basic mathematical operations - addition (+), subtraction (-), multiplication (*), and division (/).

Using these six 3's, we can create different combinations to reach 31. Here are a few possibilities:

1. 3 + 3 + 3 + 3 + 3 + 3 = 18 (this is the maximum value we can get with six 3's)
2. 3 * 3 * 3 + 3 + 3 = 30
3. 3 * 3 + 3 * 3 + 3 * 3 = 27
4. (3 + 3) * (3 + 3) + 3 = 31

As you can see, we can get close to 31 but not exactly reach it. This means that with six 3's, it is not possible to make the number 31 using the given mathematical operations.

However, if we allow some other operations like using decimal points or factorials, we might be able to find a solution. For example:

5. 3.3 * 3.3 + 3.3 + 3.3 = 31.98 (close to 31)
6. 3! + 3! + 3! + 3! + 3! + 3! = 36 (again, the maximum value we can get with six 3's)

In conclusion, it is not possible to make the number 31 exactly with six 3's using the given mathematical operations. But it is always fun to explore different possibilities and think outside the box.
