The Windows Calculator
Ever have trouble finding your hand held talking calculator when you need it right away? Sometimes they seem to hide in secret places and it can be frustrating when you can't find them.
How about using the calculator on your computer instead? I guarantee you won't ever lose this one. Just go to Start, All Programs, Accessories and choose Calculator. A little calc will pop up and you use your mouse to punch in the numbers that you need. You can also access the numbers and commands through the keyboard.
The plus (+), minus (-), multiply (x), division (/) and percent (%) signs are off to the right and it even has a fraction (1/x) and squareroot (sqrt) button in case you need those. There's also a Backspace button for when you accidentally type in the wrong thing. All these functions have keyboard entry as well.
You can go to the View menu and switch it over to a scientific calculator if you need a more advanced calc. That one comes with a bunch of other features as well, all located under the View menu. If you need any Help working the calculator, just go to the Help menu and check out the Help Topics. It's a really easy way to use a calculator when you're doing your online banking, etc.
You can also access the calculator by going to Start, Run and typing in "calc" (without the quotations).
