What does it mean instead of at the top, the power is at the bottum
Like instead of 2^4
The 4 is wrote smaller and below and beside the 2

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
(x<sub>1</sub> , y<sub>1</sub>)
and (x<sub>2</sub> , y<sub>2</sub>)
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 (x<sub>1</sub> , y<sub>1</sub>)
and (x<sub>2</sub> , y<sub>2</sub>)
the slope is (y<sub>2</sub> - y<sub>1</sub>)/(x<sub>2</sub> - x<sub>1</sub>)
Think of it as the first x ---->x<sub>1</sub>
and the second x ---- > <sub>2</sub>
