I am currently using zetamac (has customizable number ranges but doesn't allow for decimals), tradermath (seems to be made to resemble the actual test for flow but costs money unfortunately), and rankyourbrain (has decimal questions but the they appear to be too difficult to be representative).
I know there are other questions asking similar things but they seem to be dead so hoping to bump the subject in this manner! Please hit me up or comment if you know of any alternatives.

This Forum might draw quite a few people who are quite brilliant at mental arithmetic. About a month and a half ago, I discovered arithmetic dot zetamac dot com and have been obsessed with it ever since. My high score is 79 on the default settings, but that requires everything to line up and fall in perfectly. For myself, I consider 70 to be a decent run and 65 to be disappointing and 60 is where I feel every mistake I make. I learn a lot about myself by playing! I have seen online scores over 120, which is something I find mind boggling. Anybody else a regular player and kicking butt at it?
And hi! It has been a very long time since I have checked in here!
Eh, I like math but I'll pass. I suck at basic mental arithmetic most of the time, unless I know a trick of some sort. I think in orders of magnitude and crude approximations, and then use a calculator/computer to find the real answer, and then check it with my crude mental approximation to make sure I understand what's going on and that I didn't screw up.

Not need to memorise. We have tables!

I don't get this - 120 seconds and I get to do stuff like 384:6 multiple times. I tried this game 3 times and got my best score around 16. Since I teach math and I do multiplication in my head daily, 16 to your 65 seems way off.

By carefully adjusting the starting settings so that each calculation was always 1+2 I was able to get a very high score.

I always mix up 7x8 and 9x6 - never know which one is 54 and which is 56
Also 5 + 4 = 9, therefore 54 must be the product of 6 x 9, not 7 x 8.
Am I the only person in this thread who has watched Hitchhiker's Guide to the Galaxy, and therefore immediately knows that 6 x 9 = 42?

First attempt... 32.
But why would I? Hooray for shameless laziness.
This is my signature. It is neither notably poetic, nor particularly elegant, but it belongs to me.
I got 93 on my first try.
6 x 9 = 42 in base 13. Maybe that's part of the meta-joke.
