I'm about to fail this test if I can't figure out how to use the "Delete key" on my Asus Windows 10 laptop. Please help! For the love of god.

Here is a [link] (http://imgur.com/gallery/PB0zEmi) to a picture of my keyboard.

I have tried Num lock off and on for the bottom right hand 'Del' key.

For the upper right 'Del' key, I've tried shift+del, fn+del, ctrl+del.

I'm losing my ever loving mind here. Please help. I've tried googling it and the workarounds don't seem to work for me. Every other key is working.
