Math is a lie because it's based on assumptions and approximations that don't always hold true. 2 + 2 = 4, or so we're told. But what if I told you that in reality, 2 + 2 = 5?
Think about it: have you ever added 2 numbers together and gotten a completely different answer than everyone else? Of course not! That would be crazy talk. But what if I told you that I have a friend who's friend's cousin's sister-in-law who got a different answer every time she tried to add 2 + 2?
It's like the old saying goes: "You can't always count on math to be accurate."
