Want to Use a Calculator

This article shows you how to open up a calculator in your web browser, then shows you a table of features that every calculator should have.

Add

You will also notice some differences in how addition, subtraction, multiplication, and division keys appear. Once you bring up the calculator function, there is often a circle or square to give you the operations which you perform using the Menu button on the phone. Always put a number in to start and then you can add, subtract, multiply, or divide. A few phones have other operations available, but usually they are available as a download and are quite expensive compared to purchasing a calculator.

Some calculators have a percent key that essentially divides by 100, but it can do other useful things that might save you a few keystrokes. For instance, if you need to add 5% to a number (perhaps to include the sales tax on a purchase), on most calculators you can enter the original number and then press " + 5 % = ". Just make sure you understand what it does before you blindly trust it. What it is doing in this example is multiplying the original number by 0.05 and then adding the result onto the original number. (Source: www.universalclass.com)

Copy

You can enter simple formulas to add, divide, multiply, and subtract two or more numeric values. Or use the AutoSum feature to quickly total a series of values without entering them manually in a formula. After you create a formula, you can copy it into adjacent cells — no need to create the same formula over and over again.

If you don’t want to use a calculator, you may take an exam without one. However, if you choose to take an exam without a calculator, you must hand copy, date, and sign a Calculator Release Statement on exam day, which will be provided by your AP coordinator or proctor.
