In the registration i have to solve folowing math formula:
1 + (PLUS) 5 - (MINUS) 4 * (MULTIPLY BY) 5 =
I put in -14 which is correct, because multiply has higher priority that add or subtract.
So you have to calculate:
1 + 5 - (4 * 5) = 6 - 20 = -14
But this was not accepted!
So i entered the WRONG value of 10, and that was accepted!
