Help configuring the calculator desklet

[fleppmar]

Hello.

I am new to Linux, and I am starting to discover the amazing OS that is Linux.

I am running Linux Mint Cinnamon 18.1 64-bit.
I have installed the Calculator desklet from the repository, however, I can only use it with my mouse pointer.
I have tried with both num-pad and the line above the letters.

Is there any script out there that I can add to it so I can use my num-pad for input as you can on the calculator app?

Thanks!
