What are symbols and why are they used?

They are used to enable people to communicate. After all, you

are reading this answer in the form of 26 symbols (plus a few for

punctuation). The only significance for the letter "c" is that

which is accorded it by the common convention that both of us

use.

In a different context, and with a different audience, the same

letter could have meant:

  • the intercept of an equation of a straight line,
  • the constant of proportionality in a direct or inverse

    relationship,

  • the constant of integration in an indefinite integral,
  • the speed of light in vacuum,
  • 100 (Roman numeral).


Moreover, if I had written in code the same symbol could have

meant something quite different.
