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?
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.
(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).
no 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
The award winning movie "Rain Man" was based on the Idoit Savant of all Savants, still living, Kim Peek.
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.
