Can I turn my mac keyboard into a number pad?

I have a late 2008 MacBook Pro that runs on Lion. Is there any way (without using my iPod/iPhone/iPad or using a wireless number pad) to be able to turn my current keyboard into a number pad; for some reason I want to say someone told me a while back that there was a way you could do it with Fn if you turned something on in your control panel however I don't remember the tip. Any help would be greatly appreciated.

Also, this weekend I'm purchasing a new MacBook Pro that will run Mountain Lion, is there a way I can do the Number Pad on it?

How to delete a photo off of my iPhone 4S? That is not in the Camera Roll?

Ok so I have this photo of my ex boyfriend on my phone that I had put on there from Facebook a while ago. I saved the photo onto my computer from facebook, then i dragged the photo onto my phone while it was connected to itunes. It's not in my camera rool either. I tried to click on the photo but there was no trash icon to delete it. This is what I do: I click on my photos icon. And when you click on that you will see my albums.: Camera Roll, Photo Library, and New Folder. The picture is in New Folder. It is not letting me delete it from my phone. I have my phone connected to itunes now but I don't know what to do now. I don't want to sync the photos because all the photos on the computer is going to go on my phone and i don't want that.

How to use DDWRT Linksys router to create acces point or repeater?

Here is my problem:

I have suddenlink as an Internet Service Provider (ISP) and i currently use their router for my home. My home is rather large and i would like to connect my Linksys (WRT54GS) router to my main router to allow me to connect with a stronger signal and custom login details in my electronics room.
One constraint is i can't run an ethernet cable between the two routers so it would have to connect wirelessly.

My Solution (what i have tried): I have a dell inspiron 1545 win 7, and i have tethered my iphone 4 between the computer. While i had it tethered i used internet connection sharing (ICS) to repet the signal through my ethernet port and out to my xbox and to my shock it worked. I tried to do the same with ICS to my router but it was a fail.

I need serious help. I'm not a networker.
