1. it is called a subscript
it is not an actual mathematical operator, but instead is an indicator.

e.g. you often see it to label two points

(x1 , y1)
and (x2 , y2)

to state that you have two points of the form (x,y) but the x's and y's are different

e.g. if you have two points (x1 , y1)
and (x2 , y2)
the slope is (y2 - y1)/(x2 - x1)

Think of it as the first x ---->x1
and the second x ---- > 2
