### Re: guess my number

54 must be the number.

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

"What is the square root of 2? 1.4141592653589793238" Seriously, I thought it was that. Too round?

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.
