Can you tell me what this math terminology means?
What search terms could I use to find out more about this. How could I use e.g. a₁ in an equation.

In set theory, symbol → denotes a function.
f: X → Y means the function f maps the set X into the set Y.
For example, phrasing
Let f:R→R with f(x)=x²
is used to tell that f(x)=x² has set od real numbers R both as domain and codomain, that is, both argument and the result are real numbers.
