Numlock 'off' On Startup

First off, let me warn you I am in no way a computer expert. I'm happy getting the damn thing to work at all on some days.

My problem is this: whenever I start up my computer the NumLock key is always set to 'off' and it drives me nuts! I've looked for solutions on the internet but most of it is gibberish to me. Can anyone explain it to me as if I were a four year old?

I have an Acer Aspire E 15 with Windows 10 installed. Apparently I'm not the only person to have this particular problem so I figured someone has found a somewhat simple solution by now.

Thanks for any advice you may have.
