I am searching for a program that uses the same sort of language as this site that I can type up maths assignments on. I downloaded MikTex (once I installed it, the only program I could find was TeXworks), and copied and pasted a question that I posted on this site, then hit the 'play' button, but it came up with errors and I noticed that there were a heap of other 'scripts' to chose from which led me to believe it was not simply a copy and paste job.
I only know the rules that this site uses from this link MathJax basic tutorial and quick reference
Can someone recommend a program that I can type maths equations according to these rules and save as a pdf or something that I can print?
