Have any of you ever taken a rapid math course? I'd like to practice daily and be able to do arithmetic very quickly in my head. Can you recommend a course?
You mean to become a calculating prodigy?. Many idiot savants has this useful gift. Most people who have this strange ability had it from birth, including the great mathemations: Euler, Gauss, Wallis, von Neumann.... But whether a person can train himself how to do this is an interesting question. Histroy records only one such person.
I say that your victory is unlikey. You may get fast but you will never be faster than these guys, spend thy time on something else.
Just because you won't be as fast as some others is no reason you shouldn't do it. Keep looking. I have heard of courses like that, that seem to teach the ability to do massive calculations in your head, i've never caught any of the names though. I doubt you want something that extreme though, just something so you can do quick everyday calculations right? i searched for such courses one day, not of them seemed really fruitful, maybe you'll have more luck than i did though, so keep searching. maybe someone here knows of some.
I once I had a friend that was a lightning calculator he was a mathematician,
(dead now). Also while I never thought of myself as such it seems that the
person on the street might well consider me to be (in that I can do the calculation
in question while they are still looking for pencil and paper).

I once saw this program on the tele where there was this school that trained kids, average kids, to be able to do lightening fast calculations. the purpose of this school was to train the kids for a certain contest. I remember one of the challenges in the contest: 10 four-digit numbers would be flashed on a screen within a 3-second interval, then you had 3 seconds to write down the sum. The difficulty would be increased until all but one student was left. I never caught the name of the school or the name of the training that they did. Does any of this sound familiar Captain?
i assumed as muchno one wants that, not unless you're bent on breaking the some world record or somethingI don't want to be able to calculate pi out to 2000 digits.
they have books on things like that. do a search at amazon.com or barnes and nobles for things like "rapid math" or "math tips and tricks" or anything along that line. i bought one of those books a while back, never got much use from it though. maybe i wasn't diligent enough--i was an impatient person back then, if i didn't see improvement right away, i lost all resolve
When I was a 6/7-th grader I used to have fun with that. I developed a skill to square 4 digit numbers in my head rather quickly. And at times I succedded with 5 digit numbers as well. Now I am not as fast.
The award winning movie "Rain Man" was based on the Idoit Savant of all Savants, still living, Kim Peek.

I think it is more impressive to be able to solve a long mathematical problem entirely in your head than being able to multiply huge numbers instantenously.
For example, solving a wave equation PDE given the boundary value problem, with no pencil no pen. Entirely in your head! That would be an astounding feat. From what I read, Galois was able to do this to some extend.
