FSCalc on the PAC Mate

FSCalc is a multifunction calculator made for the PAC Mate. Functions include stats, trigonometry, conversions (such as metric to standard), and financial calculations.

Opening FSCalc

To open FSCalc, press F4. Press P for Programs, then press F until you hear "FSCalc" announced. Press ENTER to open FSCalc. Or, press F3 to to directly to FSCalc. (hear example)

Using FSCalc

You are automatically in the Edit field and ready to begin.

Note: One nice feature of FSCalc is that you can save your work as a text file. If you are a student and must turn in work or want to review your steps, this is a handy feature.

Your work is saved automatically.  If you press ESC to close FSCalc, the next time you go in to FSCalc, your work will still be there. To save work with a specific file name, press F2.  You will automatically go to File. Press ENTER. Press the DOWN ARROW once to save or twice to save as. The file is saved as a text document.

You may also review your work as you go by pressing the up and down arrows.

Shortcut Keys

FSCalc includes some shortcut keys to help you work faster. Press DOTS 1-4-5-6 CHORD, H for a list of shortcut keys (hear example). Shortcut keys include:

• DOTS 3-5-6 CHORD - clears display
• DOTS 1-4-6 CHORD, H - clears history
• DOTS 1-4-6 CHORD, V - clears variables

Basic Math

All four of the basic arithmetic functions can be performed using keys on the keyboard:

• Addition - DOTS 3-4-6
• Subtraction - DOTS 3-6
• Multiplication - DOTS 1-6
• Division - DOTS 3-4

To perform a basic function, simply enter the keys directly (e.g. 1+1). To hear the answer, press ENTER. (hear example)

If you press the up arrow, you will hear your equation. If you press the down arrow, you will hear your answer again. (Hear example) This work history will be saved until you press the shortcut key to erase that history (listed above).

Sample Calculations and Functions

Square root

To work a square root, enter sqrt and the number you wish to find the square root of in parentheses with no spaces:

Example: To find the square root 27, type in: sqrt(27). Press ENTER to hear the answer. (hear example)

Squaring a number

If you wish to find the square of a number, use the Pwr command. In the parentheses, include the number you want to square, then 2 for squaring. (Note: this is a power function, so you can raise the first number to any power you want by changing 2 to any other number.)

Example: To find the square of 5, type in: Pwr(5,2). Press ENTER to hear the answer. (hear example)

Conversions

There are many conversions included in the FSCalc program, including metric to standard, wind chill factors, and even numeric conversions like standard to octal or reverse (for programming).

Example: Determine how many gallons are in a 2-liter bottle of soda. You can use FSCalc to find this out by converting liters to gallons. To do so, type in: gal(2) and press ENTER to hear the answer. (hear example)

In this example, the 2 represents how many liters you are converting to the measure of gallons. The gal command automatically tells FSCalc to convert gallons to liters.
