- Write brackets {} as
`\{ and \}`

- write
**spaces**as ~ for a single space - write most math symbols using intuitive names. For instance, write phi as
`$ \phi $`

: $\phi$ - to negate a symbol, prefix it with
`\not`

. For instance, for not subset, write as`$A \not\subset B$`

which results in $A \not\subset B$ - write
**fractions**as`\frac{x}{y}`

to represent x over y: $\frac{x}{y}$ - write
**subscript**as`_{}`

and superscript as`^{}`

. For instance`$P_{23}$`

for $P_{23}$ and`$P^{34}$`

for $P^{34}$ - write
**new line**with two \ - write
**decorations**prefixing teh symbol. For instance for**x bar**write as`\bar x`

: $\bar x$
