Q&A: How do I type a division sign into a Word document?

Posted on January 10, 2023

Question from Hannah: I know this is probably a stupid question, but I just can’t figure out how to do something that seems like it should be really simple.

I’m writing an important paper for my math class and I can’t figure out how to type the division sign in Microsoft Word.

I can type the signs for all the other math operations, but I cannot for the life of me figure out how to type the division sign. It’s not on my keyboard!

Do you think this would work ok? I’d like to save some money if we can, but we really need to have this machine get (and stay) online most of all.

Question from Darryl: Several years ago I paid a friend of mine to build me a desktop computer.

This machine has an Intel CPU and 8GB of RAM. There is no video card because it’s using the integrated video on the motherboard.

This machine has worked perfectly for years but now it’s started overheating and shutting down on me. The CPU temperature reached 170 degrees before it shut down last time.

Posted on January 2, 2023

Question from Ray: I know that Microsoft Defender disables itself if it detects a second antivirus is running but that it’s supposed to automatically turn back on if you remove the other antivirus program.

Well I recently uninstalled McAfee expecting Windows Defender to turn back on, but it didn’t. I keep getting a message saying my computer is unprotected.

Why is this happening and how can I fix it? [Read more…]
