How people tried to solve the riddle

Some tried using complicated formulas, which didn't make the assignment any easier on people. Plus, we need to keep in mind that this math problem was made for a 3rd grader and not a college professor.

@Lenny_Here:

Come on guys, this is basic grade 3 stuff... /s

Answer: 15 - n {n ∈ ℤ | 1<n<15}

@Fastfingers_McGee:

15-n where n is an element of the set of integers such that 1 is less than n and n is less than 15.

For the people who don't know what that is.

@sim642:

That's some weird notation you got there. It's much more common to just write {15 - n | n ∈ ℤ, 1<n<15}.

@Rithe:

Well. It would have to be 15 - X, where 15 <= X >= 1

She can't lose more than she started with, and losing something implies at least 1

Can you figure out a solution?

The answer

In the simplest terms, the answer is less than 15.” Now that we see it, we can't believe how obvious the solution has been all along!
