    LOL wow, can you just show me how to make an operator which colors the text green and makes it gold, and then I could give parameters to it? Like a function in javascript. ``` function ranFunction(ranText) { [insert stuff here] } ``` and then running it on a string. ``` ranFunction("Parth"); ```

    `\newcommand\Parth[1]{\bf\color{green}{#1}} 500+abc+\Parth{13} =?` \[\newcommand\Parth[1]{\bf\color{green}{#1}} 500+abc+\Parth{13} =?\]

    Yes, that's what I wanted! What does the `#` mean? Does it act like a parameter or something?

    after `\newcommand ` and `\Parth` (the operator name) there is a term in square brackets that is the number of variables the operator works with the `#1` is a reference to the first variable

    Ah, nice, we have variables in typesets too.

    \[\newcommand\Unk[1]{\mathbf{#1}}\\ \Unk{UnkleRhaukus~rocks!}\]

    you can leave a variable blank with `{}` `\newcommand\intl[4]{\int\limits_{#1}^{#2}f(#3)\mathrm d#4}` `\intl ab{}z =?` \[\newcommand\intl[4]{\int\limits_{#1}^{#2}f(#3)\mathrm d#4} \intl ab{}z =?\]

    you can even have a newcommand without variables `\newcommand\something[0]{ {\tiny\color{gray} ? }} \ \something` \[\newcommand\something[0]{ {\tiny\color{gray} ? }} \ \something \]

    maybe you really want to use `\newenvironment` @ParthKohli I haven't tried that command yet

    use \(\text{\ }\boldsymbol{{boldsymbol{}}} \) instead of just \(\bf{\text {\ bf}}\) if you dont want to loose italics ``` \newcommand\Parth[1]{\boldsymbol{\color{green}{#1}}} \Parth{@ParthKohli} ``` \[\newcommand\Parth[1]{\boldsymbol{\color{green}{#1}}} \Parth{@ParthKohli}\]
