Template talk:Operator notation sidebar

The order of titles is upside-down!
The title of the notation comes in the bottom, but the titles of related notations come right under the notation's illustration.

Example:

In the Polish Notation page, the operator notation sidebar shows a Polish Notation, and there are 3 titles under it:
 * The top one: Postfix notation("Reverse Polish")
 * The middle one: Infix notation
 * The bottom one: Prefix notation("Polish")

So the sidebar effectively does a good job at introducing the wrong notation. It confused me and made me re-read the first paragraph several times.
