I think a few more problems could be added or a little time taken off. I know it's random and not everyone is going to have multiple problems that had a 1 digit number in them like I did, but the average score is 16/20 so a lot of people are finishing this easily.

26 seconds left. Tricky for me - I added columns right to left (as we were taught in school). But when I tried to invert the numbers to type them in (left to right, as required by our stupid computers), I invariably messed up the order, confused myself thoroughly, and had to re-do the addition. Ack! LOL Nice challenge!

I agree, it's too easy (or maybe it's too random).

I got all with 0:16 left, on my first try.

I was using my laptop numpad & watching a yt video in split window. I wasn't rushing at all, and made >3 mistakes.

I have finished calculus, but don't consider myself particularly bright with math - C+/B range.
