Floor and Ceiling Functions - MATH Example: How do we define the floor of 2.31? Well, it has to be an integer .. and it has to be less than or maybe equal to 2.31, right? 2 is less than 2.31 but 1 is also less than 2.31, and so is 0, and -1, -2, -3, etc. Oh no There are lots of integers less than 2.31. So which one do we choose? Choose the greatest one which is 2 in

How to Prove That 1 = 2? And therefore that 2 = 1. I know this sounds crazy, but if you follow the logic and don't already know the trick , I think you'll find that the "proof" is pretty convincing. Here's how it works: Assume that we have two variables a and b, and that: a = b; Multiply both sides by a to get: a 2 = ab; Subtract b 2 from both sides to get: a 2 - b 2
