54 must be the number.

We need more hints? How about 60.

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.

How do you defing divisibility by 6.9?

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

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.
