Math is full of symbols

In fact, some people did.There's no reason why the equals sign had to look the way it does today.At some point, it just caught on,sort of like a meme.More and more mathematicians began to use it,and eventually, it became a standard symbol for equality.Math is full of symbols.Lines,dots,arrows,English letters,Greek letters,superscripts,subscripts.It can look like an illegible jumble.It's normal to find this wealth of symbols a little intimidating and to wonder where they all came from.
