    I Prove that A:B is greater than C:D?

    From "Road to Reality" chapter 3 part two. If three ratios are known: M:N, A:B, C:D. A:B is greater than C:D if: A added to itself M times exceeds B added to itself N times and D added to itself N times exceeds C added to itself M times. Show that the ratio A:B is greater than C:D.

    Is this a fair description of mathematics (in one sentence)?

    Mathematics is a vast subject with a very long and rich history divided into many branches that usually begins by making precise and defining new intuitive rational concepts (often inspired by the perceived world or from existing mathematical or scientific theories) and develops by employing...
