nice! I suggest using an 'upside down pyramid' as cell tabbing would work better

I did it as suggested - you're right it works much better and doesn't look too bad! Thanks :)

Nice idea, maybe make it 30 seconds? So far everyone got all 15!

I'll reduce addition and subtraction to 1 minute, multiplication can stay at 2 though

This is great! Yeah, solid quiz here. Thanks for answering my question. Only small issue is the annoyance of the page bouncing down every answer in mobile. Still fun. I did the whole series.
