Hello,

Is there a FORMULA to divide a number? :o\  lol
For example,  a / b   Is there a forumla to do that? (obviously, other than "a/b"). Don't ask why I want to know this  lol

Thanks

Well, there could be (a * inverse(b)) where inverse(b) is b to the power -1. ;-)

There are certainly algorithms for division but it is generally regarded as a "primitive" operation.

One such algorithm would be to count successive subtractions of powers of b from a. (As is done in "long division").

one has certain operations such as
addition, multiplication, exponentiation, differentiation
These operations have their "inverses" such as
subtraction, division, logrithems, integration.
In some sense there are rules for the operations but the inverses are essentially trial and error. sftewng has given you the trial for division. It works.

Given A and B with A>B

N=1;
D=0;

while (B>=1) {
   while (A>B) {
      A=A-B;
      D=D+1;
      N=N+1;
      }
   A=A*10;
   D=D*10;
   }

The result of division id D, while N is the position of the decimal point.

You could explore the notion of "equivalence classes" as discussed in the preface to Roger Penrose's "The Road to Reality":
