Question

what is latex

Answer 1

Latex is the computer documentation language similar to word, but instead of typing the word, you write a code which decides the format of your document.

Answer 2

codes can be written inside `\[...\]` or `\(...\)`
like if you want to increase the font size, you can use \large or \huge
`\[\huge Hi \]` will give you \[\huge Hi \]
to decrease font size, use \small or \tiny
`\[\tiny Hi \]` will give you \[\tiny Hi \]
or you can change color of the font using \color{color name}{...}
like, `\[\color{red}{Hello}\]` gives you
\[\color{red}{Hello}\]
use any color you want.
and there are so many other formatting options that Latex supports.
