Infiniti fx problems Videos

Hello, I am a mathematician currently studying in college. That was a nice video, but I am sorry to inform you that I am going to tear apart nearly everything you said about infinity. This is because ∞ is not a REAL NUMBER, therefore you cannot treat it as a number. When you subtract ∞ from both sides you end up with ∞ - ∞, but since ∞ is not a REAL NUMBER you can not subtract by it. ∞ is an idea, not a number, so saying ∞ - ∞ = 0 is similar to saying 'brave minus brave equals zero'; it's nonsense. There is a number system that includes ∞ and -∞ as numbers known as the AFFINELY EXTENDED REAL NUMBER SYSTEM, but even in this one, ∞ - ∞ is undefined. Furthermore, the formal definition of an irrational number is any REAL NUMBER that cannot be expressed as a ratio of integers. Since ∞ is not a REAL NUMBER, it is not a RATIONAL NUMBER, nor an IRRATIONAL NUMBER. And the definition of an IMAGINARY NUMBER is a number that can be written as a real number multiplied by the imaginary unit i. ∞ can not be written as such, and therefore is not an IMAGINARY NUMBER.
