Ubuntu – Executable on Ubuntu 14.04

executable

I'm running ubuntu 14.04. how can i open an executable? I've already tried to follow the instructions on other posts about the same subject, although they're all about previous versions of ubuntu, and the instructions are too complex or me anyway. I know nothing about ubuntu, because I am new to it. Could you please explain it to me, plain and simple, how to execute a file?

thank you!

Full edit: Right click the executable file and select Properties. Then, click Permissions. The last step is to check Allow executing file as a program.
