I need to add superscript asterisks to the left side of different symbols like `+,\cdot,\leq,\mathbb{R}`

.

I read several different solutions to similar questions, which recommended either `\prescript`

, which is ugly, since there is a huge space between the asterisk and `\leq`

or `\sideset`

from `amsmath`

, which refuses to work on symbols like `+`

.

Does anyone know some universal pretty solution, which puts the asterisk neatly before this symbols?

## Best Answer

This is not simply using a "presuperscript"; what we need is to add the asterisk and keeping the meaning of the symbols; moreover, the asterisk seems needing to be nearer the symbol.

(The "h" is for "hyper", as I suspect this is for nonstandard analysis.)
