Math Bug

I found a bug in the Math program.

Apparently the question engine doesn't always agree with the mapping/grid engine.

I was on the 5th question and the question was:

((680-213)-38)/13

Which resolves to 33
The grid did NOT include ANY 3s in consecutive positions.

I think I saw it once before, but wasn't 100% sure what had happened.

In this case I'm not sure what happened. Maybe it's a bug or maybe you just overlooked that 33? By the way do you know that the answer can come diagonally? We'll investigate anyway. Thank you for reporting.

It happened again. This time - I kept the grid open. So here it is:

0 9 6 8 4 5 0 1 2 5
1 8 8 8 9 9 9 0 2 1
6 7 7 4 0 1 8 7 7 7
0 6 5 2 5 7 6 9 7 4
7 2 8 0 8 8 1 1 1 0
9 7 0 7 1 7 2 6 4 2
1 7 1 7 7 0 6 0 8 7
9 1 1 7 9 3 7 6 8 2
4 7 9 5 4 4 9 7 1 2
4 7 4 2 9 6 8 3 5 5

5th Question: 4x(720/(20+((105/15)+63)))

Answer is 32 (not found in grid)

NOTE: This is a different grid and equation than from before.

This seems like an fairly rare, truly random bug/hiccup.

Yes you are right. The answer cannot be found. We'll check the program to see how this can happen.

We really appreciate your effort for reproducing this bug. Thank you very much.

We've found the bug. It's fixed. You will be acknowledged for your contribution for reporting this bug. Thank you very much.
