Mathematical formula
$ Denote the beginning and end of the formula
$ E = mc ^ 2 $ # markdown input operation
A $ symbol indicates a mathematical formula is inline, within the line display, two $$ indicates a single line of formula
(you can learn about latex)
Einstein's mass-energy conversion equation E = MC ^ 2 $ $, reveals the relationship between quality and capacity
which is one dollar formula to solve the equation X $$ = \ {FRAC -b \ PM \ sqrt {B ^ 2 -4ac}} {2a} $$, mathematical formulas
