Complex formula & Markdown common symbols

Formula format

Inline formulas (not wrap) used $as the starting and ending character, such as: $a + b = c$ the effect is: \ (A + B = C \)

Formula block level (a single line) used $$as the starting and ending character, such as: $$a + b = c$$the effect is: \ [A + B = C \]

Using superscript ^indicates, when more than one symbol superscripts use {}package, for example:

Use the subscript _indicates, when more than one symbol superscripts use {}package, for example:
