Too hard for a #2 ? Let me know what you think about it!

Great, as a first one. Glad to see that the level is increasing a bit through the quizzes. However, I think that it would have been great to keep the same timer. I think that's currently way too easy. I'm not fast nor good at maths and I finished it in just more than one minute. I think you could easily decrease the timer by 1:30-2 minutes.

I was worried that the difficulty would be way too high for a #2 so I compensated it with a generous timer. Maybe you're right and I could bring the time to 2 minutes like the 1st quiz. I'll wait for a few more takes and see the scores/feedbacks too.

Does this pass through 27? I got to the end and never used it 🤔

Yep that's a valid answer in the chain. Dunno how you could have won without passing through it :D

I also didn't go through 27, and it's because I misread the clue at 0 as squaring rather than cubing. In my defense, the font is really small even on my laptop. By coincidence, that ends up skipping just the 27 and going straight to 9.

Maybe change the clue under 0 to ^3 instead of the superscript.

Thank you for your feedback. I edit the script with a bigger 3. I hope this will make it easier to read. Could you tell me what you think about it?

I want to avoid the (^3) form as much as possible because it would make the text not fit in the boxes :)

After some thought and talks, I changed the cube clue to another one involving a square.

Am I mad or 4+3^2 = 13, not 9 ?

You're not mad: the result is 13.

More time! It is hard enough without the time pressure--would have been so fun to see if I could get to the end, but I can't do math that fast!

Good quiz!!! I assumed 40-6 would be too high so guessed a random number and realised that 34 was a valid option...
