what does this symbol mean? ~?

A tilde has many uses from language, to math, to computing. I think this link with answer any questions:

http://en.wikipedia.org/wiki/Tilde

It is called a ’tilde’ and in different languages it changes the pronunciation of a letter that already has its own. For example, in Spanish, a tilde placed over the letter ‘n’ makes the pronunciation change to ‘nyah’ instead of ‘nah’. The word espanol has one over the ‘n’ to make it sound like “es-pan-yol” rather than “es-pan-ol”. I hope this helps.

It is a Tilde and you place it over a letter to indicate a change in pronunciation.

The symol is a question mark.

i know that double ~ over each other means “approximately” if that helps??
