Well at 73 and after some 55 years as an Engineer and physicist it's worked fine for me, Now if what you say is correct then, and given any number divided by itself is 1, and you say zero is a number, thus 0 bananas divided by 0 bananas = 1 banana. congratulations You have missed the whole point of maths, ie to describe the physical world.

As I said for me 0 and infinity are niceties, they oil calculus, help balance some equations and are convenient to represent the absence of a quantity, they cannot be divided or added. I reckon you are merely passing on what your tutors in turn blindly learnt, learn to think outside the box, and one day you might just make a significant contribution to society. I don't mean that in any condescending way

AS a note and I am sure you are aware of this, both zero and the concept of negative numbers are fairly recent additions to the toolbox, prior to this counting existed for several thousand years without them.

did I say negative? - that's another one that was produced only to oil maths, it too does not exist in nature..... try it, put 7 apples on a plate and try and take 8 away, in your world it will leave -1 apples on the plate (send me a picture).

Well since you guys are playing the pure maths game, where mine has always been applied, I think we're both right just don't mention that J is the SQRT of -1....
