Need help!

[Megahackerd]

hi folks,

got challenged by my teacher to create a software that ask the timetable in a bronze(1 to 10 numbers) silver(1 to 15 numbers) and gold (1 to 20 numbers)

they need to ask one multiplication, with the 3 levels on the same page for about 10 seconds

so what software you would use and how would you archive this?

thx

edit:
this is basically how i wanted

also at the end of the question it needs to show the answers

What language / dev environment are you working in?

What have you got done so far?

You still haven't said what language you're using!

Or shown any attempt

First work on your random numbers, then think about how you're going to time your events to show those multiplications for x seconds followed by the answer. Lastly worry about how you'd display each multiplication in a different colour.
