In the book Principia Mathematica, written by Bertrand Russell and Alfred Whitehead, about 360 pages are dedicated to proving the seemingly obvious statement that 1+1=2. While this pursuit may sound frivolous, the goal of Principia Mathematica was to formulate a number of mathematical concepts from a purely logical base, taking extremely tiny steps and starting from only the most basic of propositions to prove definitively wide aspects of math.
