How do I make the square root symbol and plus/minus symbol?

In MS Windows, go to Start - All Programs - System Tools - Character Map

When you get to Character Map, do a right-click and create a shortcut for the Desktop. Then you'll always have it near to hand.

In Character Map, select Arial font [it's the first easy one] and do a quick scan down the pages.

You'll find ± on the first page and lower down you'll find √ Maybe on the 4th page after the Arabic symbols.

Most mathematical symbols are found there. If you want something different from the Arial collection, try Symbol or Verdana fonts.

OK?

Character map.

√ <-- That's the only one I could find online haha. I don't know the code or anything for it, so just copy and paste.
