While most symbols are universal, authors of some textbooks use unconventional notation.

While most symbols are universal, authors of some textbooks use unconventional notation.

In addition to this the same symbols and even names are used in different fields to mean different things. This is particularly true of lowercase Roamn/Greek letters which are used to identify all sorts of quantities in maths and physics. There is often diambiguation with arrows, overbars or hats etc... but this is not always the case.

Also there are lots of things which have multiple different notations, this starts even at the lowest level where we can choose between using \frac{x}{y} and x / y or the divide symbol.
