... but does anyone know what it is called when you have three, four, five digits you can use.. I only know it as base 3, base 4... are there proper terms for it?

and are there proper symbols for if you want, say, base 13, for 10, 11 and 12? If there are, we may as well use that, but if not we can make some up no problems.

I was going to introduce Alex to binary tomorrow on APD but ah... I couldnt wait *blush* and we started last night... and carried on this morning... lol and no doubt will do more later and tomorrow too!! Yeahy! :oops:

Thanks in anticipation, Beth xxx

oooh forgot we had an off topic forum, is it possible to move the post? Sorry! :oops:

After binary comes ternary, quaternary, quinary, senary, septenary, octal, nonary, decimal, undecimal, duodecimal, don't know beyond that.

Numbers above 9 are usually written as letters, starting with 'A' for 10.

BTW, don't forget balanced ternary, the coolest base of all.

Here's a link to the mathworld site: http://mathworld.wolfram.com/Base.html

Scroll down a bit for a table showing bases 1-12, 16, 20, and 60.  Can't give you any more, as it doesn't seem there are real rules for it.

oooh thanks! This looks cool! I'm afraid I dont know what balanced ternary is, but I'm off to find out

Consider this moved

Thanks Gareth :grin:

I know 16 is hexadecimal.  :smile:
