0 can’t be a number because numbers refer to quantities and there is no quantity that does not exist. If you look at the history of mathematics you will see zero did not exist for a long time as a digit and when it was added it was a dot and then a zero as we know and only to make calculations and working with bigger numbers easier.10 is a number and so is 100 but 0 or 000 is not a number(obviously) but a digit so don’t come up with your advanced mathematics bullshit. 0 is not a number.
This is all known, especially the history of numbers. But for the not very old number theory the 0 belongs together with the negative numbers to the so-called “integer numbers”.
To be fair…I am not an expert on mathematics so I can’t say…I kind of spoke out of turn there since I don’t really know…I am sorry if I came across as arrogant friend(I was arrogant).
I might even be wrong on this necessity of tying mathematics of quantities since mathematics is also useful as a unit or proportion, for example in the little calculus I know, where you can measure acceleration or uneven spaces and, as far as formal part is concerned, you don’t even need ‘numbers’ to do it but plots and then you must calculate with algebra afterwards.
hope you are ok
In our culture, numbers have long since become functions. They are no longer numbers in the former sense. Letters can, indeed should, also have a large place in them. So it’s okay if you post an “h”.
If you really want to practice programming professionally, HTML, CSS, etc. and even Javascript are not enough. Java, Perl, C etc. are sufficient.
Well, that’s another topic. So let’s get back to the topic of this thread.
I said that in our culture numbers have become functions. There has never been such a development in relation to numbers before.
And you brought up “Algebra”. It comes originally from another culture, but has been further developed in our culture and incorporated into the overall structure of functions. With us the term has been extended to links of a general kind, so-called “algebraic structures”, and so there is a lattice algebra, a switching algebra and other algebras - yes, one has to speak of algebras (plural!) by now -, and also inequalities actually belong to algebra. Ordinary algebra does not want to teach the pure calculation of numbers (see: arithmetic), but rather general rules of connection (therefore it often uses so-called “general numbers”, which are expressed by letters); it deals with numbers up to the complex numbers, and this is what I wanted to express with the first picture: the Gaussian number plane.
The illustrated examples in the coordinate axes are really only meant as an illustration for the fact that the occidental mathematics has become the mathematics of the world, which means just among other things that numbers are regarded only as functions.
