manuelemacchia/math-latex ? reverse-engineered prompt

I want a clean one page quick reference sheet for AMS LaTeX amsmath that I can print or share as a PDF.

Make it easy to skim, with the most common commands, symbols, and math writing patterns people actually use in LaTeX. It should feel like a handy cheat sheet, not a full manual, and it should be organized clearly so someone can find what they need fast.

Please include the TeX source and make sure it compiles into a polished PDF. Keep the layout neat and readable, with good spacing and a simple professional style. If you need to check the latest documentation online for a command or symbol, go ahead and do that.
