Windows7 Calculator: More than Meets the Eye

Windows7 Calculator

Did you know your Windows7 calculator could look like this?

At first glance, the Windows7 calculator seems the same as every version offered in Windows before. However, if you take a little time to explore, you’ll soon find there is much more to the calculator than ever before.

What do you do when you need a scientific, programming, or statistics calculator? When you need to, how do you calculate your mortgage, a vehicle lease, or the fuel economy of your vehicle? In the past you would probably turn to special online calculators, or complicated spreadsheets to figure things out.

But now you don’t need to do that. Instead, whip out your trusty Windows7 calculator, and calculate virtually any equation or situation. To change the way your calculator behaves, change the settings under the View menu.

Different Types of Calculators

Basic Calculator: When you first start the calculator, it opens as a basic calculator, allowing you perform all the normal functions you’re used to. You can always return to the basic calculator from any other setting by pressing ALT + 1.

Scientific Calculator: To access the scientific calculator go to View > Scientific. Or, you can press ALT + 2.

Programmer Calculator: To access the programmer calculator go to View > Programmer. Or, you can press ALT + 3.

Statistics Calculator: To access this calculator go to View > Statistics, or press ALT + 4.

Different Calculation Modes

Aside from 4 different types of calculators, you can also choose from different calculation “modes” to get the most out of your calculator. These are all located under the View Menu, toward the bottom of the list.

Unit Conversion: Whenever you are looking to convert something, this is the calculator you want. This mode allows you to calculate one type of unit of measurement into another type. For example, easily convert an angle into a degree, gradian, or radian. Or, calculate the area of something into square meters, or better yet, square millimeters. To quickly access this function, press CTRL + U.

Date Calculation: Want to quickly calculate the difference between two dates? This calculator mode makes it easy. Just put in the two dates, and it will show you

Worksheets: When you want to calculate your mortgage, vehicle lease, or fuel economy, you’ll want to use these easy worksheets. Unfortunately, there are no shortcut keys for Worksheets. You will find them located at the bottom of the View Menu.

Mixing Calculations

Additionally, you can mix-up the functionality of your calculator, so that it’s unique to your specific needs. To do this, activate a specific calculator type and a specific mode. For example, you can change your calculator to a scientific calculator, and activate the date calculation mode so that you can quickly do either type of calculation.

Any of the calculators and modes can be mixed together, so play around with your Windows7 calculator settings. Before long you’ll have it custom tweaked for your needs, and you’ll never again seek out an online calculator or turn to a complicated spreadsheet for your calculation needs.

How to Save a Wet Phone – The Rice Trick

If your phone gets wet, do you know what to do to save it?

As soon as you hear the splash, your stomach flips, your heart pounds, and your mind races thinking of all the important items on your phone that you haven’t backed up. If you’ve ever had a wet phone, you know this feeling all too well.

When faced with this situation, there is one crucial step you can take to help prevent disaster, and all it takes is something you probably have at home already – rice.

Please note the most important factor in saving your phone is time. The longer you wait, the more time the liquid has to penetrate the internal workings of your phone. To greatly increase your chances of success, you must act as soon as possible.

Disclaimer: This trick isn’t always guaranteed to work, and depends on the severity of the incident. However, I have seen rice perform miracles on a digital camera that fell into a river, so it can work if you act fast enough.

Once you realize your phone is soaked, follow these steps:

  • Turn off the phone.
  • Dry the outside very well, using a clean, dry, absorbent cloth.
  • Remove any external connections, such as the charger.
  • Open the case, removing as much of the cover as possible (take care not to break your case).
  • Remove the battery.
  • Remove the SIM card (if applicable).
  • If possible, use a wet / dry vacuum to remove any excess moisture. DO NOT use a hair dryer to dry your phone, it could damage your device.
  • Get a Tupperware container or plastic bag, and partially fill it with rice (any type works). Place the phone in the container, and then cover the phone completely with more rice.
  • Let sit overnight. (24 hours is preferable, if you can go that long without your phone.)

Tip! Once in rice, rotate your device every hour or two, turning it different ways so that the water has a chance to escape your phone.

Once the phone has sat overnight, place the phone on a towel, paper towels, or something else absorbent, and then let it sit for a few minutes, allowing any excess moisture to be absorbed by the towel.

Clean and dry your phone, and put it back together. See if it works. If it does not, take the battery out and put it on the charger. If it works without the battery, you need to replace your battery.

The “rice trick” is a great quick-fix solution for dealing with a wet phone. However, if you are more accident prone, and tend to get your phone wet a lot, you may want to consider another option – Liquipel.

Relatively inexpensive, starting at around $59 per device, Liquipel is a lightweight, protective coating that covers your phone inside and out. With Liquipel, when your phone gets wet, the liquid beads-up and rolls off, protecting your phone because the liquid doesn’t have a chance to penetrate any parts or pieces.
For more information about Liquipel, visit their website, or check out this video.
