How can learning about powerpoint help me in the real world?

PPT will help me in the real world when I have to give a presentation in college.

I would show my presentation, not just any way-powerpoint style!

With powerpoint, I can save paper, because I'm not using word, then printing out, then sticking it to posterboard; using powerpoint is being eco-friendly.

With powerpoint, I can make informational presentations or photo presentations.

I can make powerpoints just for fun during my spare time.

I can use powerpoint all the ways above and more beyond.
