We will just be looking at the general concept. In a future post I will show you an implementation of this…mathowl in #hive-196387 • 2 years agoResearch diaries #15: Going down rabbit holesIn math everything you do has always to be consistent with the rules of logic. But the real goal of math is finding structure inside the logic.
