Hi,

I want to calculate *(81/10)^2*.

However, after I typed *81/10*, I remembered to add a bracket to surround *81/10*. Is there one way to do some trick to save this bracket?

Actually I can *Ctrl+A* to move to the first character of this line. I want the other solution.

(1) 81/10 * 81/10 (2) Enter 81/10 The result gets saved in it Now, it^2 -- Vikraman
