playing with numbers
Ok, here an easy one for starters:
1, 3, 4, 6 make 24 restrictions: you MUST use every number EXACT once. you may only use +(addition)  (substraction) * (multiplication) /(division) without restrictions on quantity (so no powers or other mathematical functions). numbers may not be combined e.g 1 and 3 cannot make 13 or 31. example: (4*6)/(31)=12 Your goal is to make 24. michael

Well the question is posed for base 10...but since the numbers are smaller than 7, you may in addition try base 7 and up if you wish... hehe

I've had pm's me with a hexadecimal solution. Congrats on finding those, though that wasn't too tough.
I have a solution in base 10, and that was how i initially intended my question michael

[FONT=courier new] Then it must be the something rational which gives the whole number (24) in the latter [/FONT]

Are we correct in assuming that the digit "0" is excluded from use and that the decimal point "," (or "." for the yanks) is also not used?

I assume you ask weither fractions are allowed.
Nothing forbids you to do 1*3*6=18 which is exactly the same as doing 6/(1/3)=18 only there you have 1/3=0.333333333333... as a subresult. Use of devision is allowed so consequently also use of fractions. michael

What I am asking is:
Is 10 not equal to using 1? I know spliting hairs. Also, is .1 or .6 allowed instead of 1 or 6? I am just looking for a way around the rules.

No those things aren't allowed.
