I often wondered about the continued existence of the division sign. Not only is it redundant, it is confusing.
A search of the net gave me this:
Part of the IT standards and organizations glossary:
The division sign resembles a dash or double dash with a dot above and a dot below (÷). It is equivalent to the words “divided by.” This symbol is found mainly in arithmetic texts at the elementary-school level. It is rarely used by professional or academic mathematicians, scientists, or engineers.
Well, even though the outside world (the real world) uses / (as in spreadsheets and computer keyboards)or “dividend” over “divisor”, as in formulae and algebra generally, my guess is that this looks too much like a fraction !!!!!
(which of course is not a number, or at best a very weird number).
