Re: guess my number

54 must be the number.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Re: guess my number

OK!  I see now.  1-100 = -99 and it's even divisible by 3.


Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Re: guess my number

There is no number divisible by 6.9. Divisibility is defined on integers only.

Re: guess my number

Why not define divisibility by:  b divides a means a/b is an integer.  Then for example (3/5)/(3/10)=2
and (.8)/(.2)=4 and (-.9)/(.3)=-3.   So we could also say b divides a if and only if there exists an
integer k such that a=kb; that is,  a is an integral multiple of b.  smile
