subtraction of two irrational numbers to get a rational Say you have a number like $\pi$ or e. Is it possible to subtract another number from it and end up with a rational number? I mean I guess you could write an equation like $\pi-x=3$ But could there ever be a solution for x (that we could know and write out)?
Correction: Any number besides the irrational number itself. Damn math ppl are too quick..

.223456789101112131415...  -  .123456789101112131415... = .1
