Imagine the greatest integer function as a step(which is also what its graph looks like). If you input a number in the function it would tell you what integer floor you crossed to get to that number. E.g- [2.9] -> the function will tell us we just crossed floor number 2. [0.6]-> This will tell that you just crossed the ground floor that is 0th floor. [-1.4]-> This will tell that you have crossed the first floor of the basement that is -1 and you are heading towards the ground floor. Remember that the building is infinitely tall both below and above the ground! :)

The best and precise explanation Sir! Thank you very much!

It's basically mathematical snakes and ladders. One thing I found out was that it is helpful to remember that f(x) is still y. The problem I had while learning this was treating the greatest value as a value of X on a number line instead of a value of Y. No one explains this and just assumes you got that part. I think it is helpful to teach so that the full structure of the equation is full understood.

gracias amigo, el pendejo de mi profesor no se supo explicar con la tarea que nos dejo y tuve que encontrar la respuesta aquí, por lo que agradezco tu explicación y ayuda

I think you forgot the most important part of the problem here.
[[-2.3]] = -3
Some people might think it's 2.

Thanks but can i understand the concept they were going with like why they made a function like this

[sedenions]

Could somebody explain why f(x) = [[x-8]] has nonremovable discontinuities at each integer k? I think I have an intuition why based on the graph, but what exactly can I plug in to realize this?
