powerOne™ 8 Infinity Softworks Mathematics (One- and Two-Variable Functions) The powerOne calculator can be used only in standard input mode. Standard input mode math is performed by alternating chains of values and operations. Math functions are either one or two variable. Two-variable math, such as add, subtract, multiply and divide, take two variables to compute. One-variable functions, such as square root and reciprocal (1/x), need only one variable to calculate.
powerOne™ 9 Infinity Softworks The following are two-variable examples: Operation Example Keystroke Addition 8+3 8 [+] 3 [=] Subtraction 8–3 8 [–] 3 [=] Multiplication 8x3 8 [x] 3 [=] Division 8÷3 8 [÷] 3 [=] Power 3 [power] 4 [=] ♦ 34 Percent 350 [x] 15 [%x] ♦ 15% of 350 [=] Percent ratio ♦ 9 is what percent of 9 [÷] 25 [%x] [=] 25 Percent add22.95 + 6% 22.95 [+] 6 [%x] on [=] ♦ sales tax Percent 39.99 less 39.99 [–] 10 [%x] discount [=] ♦ 10% Answer 11.00 5.00 24.00 2.67 81.00 52.50 36.00 24.33 35.

Memory The powerOne calculator has one memory location, plus the system clipboard. To access a memory location, use the store (M+), recall (MR), and clear (MC) functions.
powerOne™ 11 Infinity Softworks application to another. Recall information from the system clipboard by selecting paste from the edit menu. Memory Arithmetic The powerOne calculator lets you easily add a string of subtotals together in the memory location. To do this, enter the computation and select M+. Then enter the next computation and M+ again. For example, to calculate (3 x 5) + (8 x 2): Key Display Comments Memory Clear 0. Tap this to clear the memory location 3x5= 15. M+ 15.
powerOne™ 12 Infinity Softworks information entered in the main screen is the same as information in the input screen. For example, if a computation is begun in the main screen, it can be completed in the input screen. For more information on the input screen, see the section on Using the Worksheets. Menus The main and input screens have two menus. Access the menus by selecting the menu button to the left of the Graffiti input area.
powerOne™ 13 Infinity Softworks Using the Worksheets The powerOne™ calculator uses worksheets to perform advanced functions. This section details general use. See the section on each worksheet for details on that specific computation. Finally, see the appendix for information on errors. Accessing the Worksheets To access a worksheet, select the main screen button labeled “Business” or “General” and choose the desired computation.
powerOne™ 14 Infinity Softworks The computation display for each worksheet is also similar. For most worksheets, the data is set in column form: Compute column Label column Value column To enter a value, tap on the label or value column, enter it in the entry screen, and save. To compute a value, tap the “CPT” label next to the data to compute. Entering Data In the worksheets, data is entered using the input screen, date selector or time selector, depending on the type of data requested.
powerOne™ 15 Infinity Softworks When a value is selected, that value appears in the input screen. The keyed function buttons work similar to those in the main calculator. The only difference is memory, which is accessed by selecting the “mem” button and choosing the function from the pop-up list. See Performing Arithmetic for help with understanding mathematical functions.
powerOne™ 16 Infinity Softworks Sales Tax The sales tax worksheet computes tax before or after sales tax, or the tax rate itself. • • • Before Tax: the amount before taxes. Tax Rate%: the tax rate as a percentage. After Tax: the amount after taxes. Example: The local tax rate is 5.5% You have a maximum of $70 to spend on clothing.
powerOne™ 17 Infinity Softworks Calendar The calendar worksheet computes both days between dates and a date based on a given number of days. • • • Date 1: the date to compute from. Date 2: the date to compute to. Difference: the difference in number of days. Example: Vacation begins on October 15, 1999. Today is August 18, 1999.
powerOne™ 18 Infinity Softworks Markup/Discount The markup/discount worksheet computes sales changes. • • • • Method: whether you are computing a markup or a discount. Orig Price: the original price of the product. Percent%: the percentage to markup or discount expressed as a percent. New Price: the new price of the product after the market or discount. Example: The clothing is sold at a 25% discount. What is the current price if the original price is $29.
powerOne™ 19 Infinity Softworks Percent Change This worksheet performs percentage change computations with either one or more compounding periods: • • • • Old: the old value. New: the new value. Change%: the percentage changed. For example, an 8.125% change would be entered as “8.125”. A positive value represents an increase while a negative one represents a decrease. Periods: the number of periods. Example: Over 4 years, sales increased from $45 million to $115 million.
powerOne™ 20 Infinity Softworks Compute the percent change by selecting “CPT” on the Change% line. Sales have increased 26.44% per year, comparing favorably to the 20% industry pace.
powerOne™ 21 Infinity Softworks Tip The tip calculator computes tip, total bills, and performs bill splitting functions. • • • • • • Bill: the bill amount before tip. Tip%: the tip percentage chosen from the pop-up list. Tip Amount: the tip amount. Total: the total amount including the tip. #People: the number of people paying for the meal. Ttl/Person: the total per person, split evenly among the people paying for the meal. The tip computation calculates from the top, down.
powerOne™ 22 Infinity Softworks Example: At a team business lunch, your four person team (including you) goes to lunch. The total bill is $45. With a 15% tip, what should each person contribute? Key Entry Comments Clear… Sets the display to its default values Bill 45 Tip% 15 Compute the total per person (Ttl/Person) by selecting “CPT” on the same line. Each person should contribute $12.94. Example: For the example above, the company will pay the entire bill instead.
powerOne™ 23 Infinity Softworks Calculation Log The calculation log displays computations as they are entered, which makes doublechecking easier. For standard input mode, the calculations are displayed as they are entered. To scroll the list, choose the scroll arrows or scroll buttons.
powerOne™ 24 Infinity Softworks Appendix The appendix contains additional information pertinent to the use of the powerOne calculator. Graffiti® Input The powerOne calculator supports Graffiti® entry for both the main and input screens. To learn how to draw each character, see your Palm device user manual.
powerOne™ 25 Infinity Softworks Note that the Graffiti shift indicator is in the view window both on the main and input screens. Also, certain characters are not allowed. These keystrokes and their accompanying shift indicator are ignored. For instance, capital letters are not supported so the Graffiti shift indicator for shift or caps lock is not displayed. Error Cases Error messages appear when calculations cannot be successfully completed.
