There are several calculators that come with Windows. Their capabilities range from performing simple calculations (like add, subtract, multiply, and divide) to more complicated calculations (like trigonometric functions, logarithms, and exponentiation). You can even perform certain conversions with the calculators, perform mortgage analyses, and work with dates.

To start the calculator (even though there are several calculators, they are technically different views of one "super" calculator), click **Start** | **All Programs** | **Accessories** | **Calculator** if you are using Windows 7. Since many people use the numeric keypad with Calculator (instead of the mouse), you may find it easier to just press the Windows key on your keyboard, type "calc" (without the quotes), and press **Enter**.

If you are using Windows 8, finding the calculator is a bit more vexing. The easiest way is to start from the Start screen and use the search capabilities to look for "calc." The app that is located will be the calculator you want to run.

The type of calculator that appears depends on the type of calculator that was used last. This tip is specific to the Standard calculator, so whichever way you invoke it you'll see the following: (See Figure 1.)

** Figure 1.** The Standard calculator.

If another type of calculator appears, click **View | Standard** to get the one that matches what's shown in the figure. As you can see, the Standard calculator provides the following features:

- decimal digits 0 through 9, and the decimal point
- operations: add, subtract, multiply, divide, percentage, reciprocal, square root, change sign, equals
- clear, clear last entry, backspace
- memory functions

You can use the mouse to click the on-screen keys or you can use the keyboard to cause the corresponding button to be pressed. (For buttons not on the keyboard you must use the mouse.) The Standard calculator does *not* use operator precedence like what you learned in school (i.e., how multiplication and division are performed before addition and subtraction). Rather, operations are performed in the order entered. So, for example, if you enter **3 + 2 * 4 =** you'll get the answer 20 instead of 11.

The calculator has an internal memory where you can temporarily store a value. Let's say that you perform a calculation whose value you want to use in another calculation. Instead of trying to remember it or write it down, just click **MS** (Memory Store) to store the value in memory. Then whenever you want to use what's in memory, click the **MR** (Memory Recall) button. For example, say that you calculate **22 / 7 =** and get the number 3.142857142857143. Click **MS** to store this in memory. Now if you want to take this number times several other numbers you can just click **MR** each time you want to use it instead of having to type it in every time.

You can also add and subtract to/from memory. For example, if you store the number 5 in memory, you can then press **10 M+** and you'll discover (by clicking MR) that the number 15 is now in memory—the calculator added 10 to the 5 that was already there. You click the **MC** (Memory Clear) button to clear what's in memory.

The pertinent section of the Tip reads, "The Standard calculator does not use operator precedence like what you learned in school (i.e., how multiplication and division are performed before addition and subtraction). Rather, operations are performed in the order entered. So, for example, if you enter 3 + 2 * 4 = you'll get the answer 20 instead of 11."

Sorry:

3 + 2*4 gives 11 NOT 20
