Numbers: Make numbers negative

numbers

In Numbers, how can I convert a number to negative.

E.g.

200
233
186

Becomes

-200 
-233 
-186

In Excel, you can use tools like Paste Special, but these don't exist in Numbers.

A workaround is to create a column with formulas like "=-1 * A1", then copy and "Paste Formula Results" (⇧⌘V). But I'm sure there are better solutions.
