Mathematics is the study of things you can convince people are true without physical evidence.

  I like this one. Succinct and to the point. However this would also include religion :\

    Two different religionists can have a conversation and agree on what is true?

      Within the lens of the other religion probably. Except from hardcore zealots, religious people often agree on true things that they find in common between religions (eg idol worship being a sin, murder, adultery, etc etc).

    Not if you added "...using only pure logic". Religions do not convince with pure logic.

      The problem is that now you need to define what "pure logic" is. Here's my definition: Math is the study of intersubjective knowledge.
