Input your problem. Here are the possible places to put the operation (+, -, x, /): 1 x 34567; 12 x 4567; 123 x 567; 1234 x 67; 12345 x 7. You can have up to 7 characters in your problem, including the operation.
I may add decimals and maybe fractions, but this is going to remain mostly basic because I don't want you guys using this to cheat on your homework (tho you probably will). Also this is REALLY hard to program and tho it may not look like it, I am a seasoned programmer. @colton129 for convincing me to keep this basic.
