I've leaned a way to count that on my fingers and it's great for providing some distraction at a graduation ceremony. Frankly, after base 10 I'd go to base 6 = 2 x 3. Then maybe progress to base 30 = 2 x 3 x 5. The prime factors just seem easier for me to deal with. -Dan

Is it really going to save much? I can't see any need to shave a digit or two off figures in the world. Certainly not when there's re'education costs. And if you are trying to work out what power of twelve you need for 37 million, you are working in base 10 and converting to base 12 which is terriblly inefficient.

If you only meant that it takes fewer symbols to encode (large) numbers, why not use base one million? For a reasonable definition of "most efficient" the most efficient integer base is 3. But there are many, many ways to define this, and you can come up with lots of different answers.

yes but it is sometimes needed because I will come across scientific notation in base 10 and want to convert it to base 12.

I would say though that converting 37 trillion from base 10 to base 12 takes many less mod 12^x equations than converting that same number to binary using mod 2^x.

as for saving digits if you take 1 trillion, that is 10^12. That same 13 digit number expressed in base 12 I bet will have many less digits because powers of 12 go up much faster than powers of 10. It might not have an effect much in tens and hundreds but as you go to thousands and millions and above it really takes effect. In the same way binary numbers are the longest because 2^x is the slowest of the integer exponential functions(by that I mean some integer taken to some power that doesn't have to be an integer)

We almost alway write 1 trillion, or 2.5 trillion or something similar. The main use for binary is in computers where it is used because it is easiest to tell whether a bit is on or off without error. We might be able to do ternary arithmetic in computing now (and maybe a little more at a push), but binary dovetails nicely with the logical side of computing too.

I hope that is hypothetical, because if you do talk like that, you and your momma can use whatever system you please.

In essence we use use ALL bases already.

Perfect. Digits MEANS fingers.
