Hi does anyone of you know the coding for user to key in decimal value (rounded
off to 2 decimal places) and the Flash software generate whether the answer is
right or wrong? Also, it will include a diagram with values that make up a
Mathematical formula.

me please. Hehe. Thank you!!

One way you can do it is by multiplying the user value and the answer value by
100, then rounding the two values and comparing them...

if(Math.round(rightAnswer*100) == Math.round(Number(userAnswer)*100)) {
trace("Right Answer");
} else {
trace("Wrong Answer);
}
