This is cool. When it's in 'all operators' mode it's challenging!
One thing that I noticed is that there's a timer. Depending on your target audience, you might want to make that optional.
My son is 7 and finds the timer on Zetamac creates unnecessary stress. So I made something simpler for him that just shows a fixed number of problems (with no time limit), and uses a cookie to track the streak length: https://math.twilam.com/

If you want another tough challenge, try division operators with longer equations and advanced division enabled. Quite evil at times.
Thanks for feedback on the timer, that seems to be common so I'm going to work on getting an alternative option out soon.
