Stuck on primes

Still working is as a problem of making an efficient , finite number line. A number line that has to accomplish two tasks, make groups and unmake groups evenly. Whole number multiply and fractional multiply have to match. But still stuck. The idea that we can let the number line go to infinity and still have a prime theory is circumspect. I think we can get a theory that says let the number line go to the next almost, orthogonality.
