Fix or rewrite order-of-operations question generator in mathcards.c
completed by: Aviral Dasgupta
mentors: David Bruce
Tuxmath supports questions with multiple operators and operands, but the existing implementation has a bug - it sometimes creates questions with multiple correct answers, only one of which is the "real" correct answer to the program.
The function is:
generate_random_ooo_card_of_length(), and it starts at line 1603 in mathcards.c
