# Anyone know how we can improve our mental math skills?

 P: 54 The other day I decided to calculate 1.225 x 36 in my head (this was a calculation in one of my problem sets) and I found that it took me a lot longer than I originally thought. So I was wondering if there was any sort of strategy to gradually improve this skill. Here's a strategy I am beginning to use: Before I go to sleep, I come up with with 7 problems (written down) to do in my head (simple ones like 23 + 43 and 346 - 987) and then check the answers with a basic calculator. Then, with my eyes closed, I do one hard problem (e.g. 3423 x 1490) so I can actually fall asleep. I've gotten considerably better with only a few weeks of doing this. But are there other strategies? Thanks.

And what to wear when we do all these mental calisthenics.

## Anyone know how we can improve our mental math skills?

The only mental math I do is rough estimation, and I've gotten pretty good at it I think. It just takes practice and knowing how to approximate certain numbers and how to correct for that approximation.

But exact mental arithmetic? No way. I have better things to do.
 P: 655 If you are really serious about mental calculation, check out these kids (watch through at least 1:25-1:40). http://www.youtube.com/watch?v=EueFhYZ4HxI They have trained so much with an abacus, that they can take away the abacus and do fast calculations via muscle memory by moving their hands on an imaginary abacus in the air.

What to wear is pretty obvious. We should wear math shirts.

Usually, when I do these calculations in my head (such as 1.225 x 36) I break the calculation up into many simple approximate calculations. I'll break it up as 1x36 + 0.250x36 = 45. Not a bad approximation to 44.1. But then again, I reckon most people do this.
 P: 247 Dunno about making it better, maybe just faster, but check out Vedic math. It's really cool, I've just never taken the time to learn to use it. I think www.vedicmaths.org works but I'm not sure...
 P: 5 If you're really feeling diligent about this, here's a website I found a while ago: The Shortest Short-Cut It's complicated, but it looks kind of cool.

Dunno, I heard this was a scam
 P: 247 It's not, try it out, its pretty cool.
 P: 2 I can say that I'm not an expert, all I need to do for improvements is practice, practice and practice. Always challenge yourself and learn from it.

Haha, that's true.

If you want to do that, read a psychology article before bed. And just before bed, look up an assignment question, and go to bed. Solve that question in your head while in bed with your eyes closed.

Kind of what I do.
