That wasn’t an answer. That was a deflection. Why do you think infinity isn’t a number? A lot of people are told this in middle school and high school mathematics, and it is true that infinity is not a real number, but this can lead to the misconception that infinity isn’t a number.

But… Infinity has many practical applications, the least of which are limits, differentiation, and integrals in calculus, as well as its opposite infinitesimals. There are many scientific and engineering principles that rely on these mathematical functions. That’s a silly thing to think :p
