I was doing math homework and wanted to find out what means, so I entered the symbol in Google Search.

However, I got no search results. How can I use Google to find out what symbols mean?

Wikipedia often has lovely tables you can find. I simply searched table of math symbols and I got to this page: List of Mathematical Symbols

I then took the symbol and hit Ctrl + F and entered in the symbol () and I was taken right to the symbol.

SymbolHound also helps.

It got me an answer when I wanted to know what => means in Scala language. But your particular query got useless results.
