Hey guys,
So I've been making a few simple maths programs to practice. I made this one as a simple addition/subtraction/multiplication/division tester. It tests addition/subtraction between 1-100 and the twelve times tables for multiplication and division.
I think it's just cos I scripted it a stupid way, but I'm having a few problems and I haven't been able to get it working. Firstly, I'm not entirely sure how to allow a minus sign in the answer box without seemingly upsetting everything. I thought it would just be:
answerBox.restrict = "0-9\\-\\";
or something similar but apparently that messes eveyrthing up when I try. Also, I used a simple 0 or 1 chance mechanic to decide whether or not it would be add/sub or mult/div, then I used the same mechanic to choose "add or sub", or "mult or div". The problem is I only ever get addition or subtraction, it never creates a multiplication or division question (even though I get roughyl 50/50 of add and sub, so the mechanic is working).
Also, it sometimes tells me an answer is wrong when it's right, like a simple addition of 10 + 3 and I give the answer as 13 and it says it's wrong.
I'm not getting ANY error messages or warnings in the compile errors section.
So basically my questions are : is this the best way to make this program? (I'm sure it isn't)
: why won't it display the mult/div ones?
: how do I allow a minus sign while restricting the text input into the answer box?
: why does it sometimes tell me that certain correct answers are wrong?
Thanks, here is the code. Ignore the "emoticon face", that's just a movieclip picture that appears happy or angry whether they are right or wrong
