Performing Arithmetic Performing Arithmetic Functions are available either on the screen or from the list displayed when the “func” button is selected. Select that button to display the list. Other buttons function as standard calculator buttons. Input Mode This calculator can be used in "order of operations" mode or chain calculation mode.
Performing Arithmetic 3 3 × 8.5 3 8.5 = 52.5 i.e. 27 + (3 x 8.5) The number of decimal places displayed depends on the decimal setting. See the section on Calculator Settings for more information. Chain Input Mode This is the input mode used by many business calculators. In this input mode math is performed by alternating chains of values and operations. Each operation is evaluated as it is entered.
Performing Arithmetic 5 35 6 356 . or , 356. 9 356.9 6 356.96 +/– -356.96 Depends on the number format The decimal point can either be displayed as a period or as a comma. This depends on the number format mode used. See your device owner’s manual for more details. The following are number entry functions: Operation Example Comments Number Decimal point 0-9 .
Performing Arithmetic The Backspace (←) button allows for editing of numbers as they are entered. Tapping this button removes the last digit entered (i.e., 54.32 becomes 54.3). Tapping the Clear Entry/Clear (CE/C) button once clears only the currently entered number. Tapping it a second time clears the entire computation. Mathematics Math functions are either one or two variable. Two-variable math, such as add, subtract, multiply and divide, take two variables to compute.

Memory Locations To store to a memory location, enter the number, select “MEM”, and finally “Store”. To recall the value, select “Recall”. To clear the memory location, choose “Clear”.
Skins/Personalized Displays Skins/Personalized Displays Skins offer a personal look to the main and input calculators. Some skins offer a different button layout, offering the advanced mathematics functions in drop down lists or giving access to programmable buttons, which can be changed in the preferences screen. Still other skins offer different color schemes. Free skins are available at Infinity Softworks’ web site. To learn more, select the “powerOne” button in the application, then choose “Skins”.
Calculator Settings Calculator Settings The Preferences screen sets preferences for the main and input calculators. The templates have their own preferences, detailed in the section on Using the Templates. To access the calculator settings, go to the main calculator display and choose “Preferences” from the powerOne button or “Options” menu. Input Mode Set the desired input mode by choosing a setting from the popup list. There are three possible input modes: • Order of Op.
Calculator Settings places: the number of significant digits displayed is 1+ the decimal setting. Display Mode There are three display modes: normal, scientific and engineering. In normal mode, numbers appear as they are entered. In scientific mode, numbers are always displayed in scientific notation and likewise, in engineering mode numbers are always displayed in engineering format. Trig Mode When using trigonometric functions, either degrees or radians can be used.
Using the Templates Using the Templates Templates are used to perform business and calendar computations. This section details their general use. See the section on each template for details on that specific computation. Accessing the Templates To access a template, choose a category from the template bar in the top, right-hand corner of the display. This list scrolls right and left with the scroll arrows. For faster access, choose the template quick hit button to the right of the template bar.
Using the Templates Once downloaded, synchronize the add-on template set to the device’s main memory (not to an expansion card) and run the application. The template set will be imported automatically. To delete the add-on templates, enter any template in the set, select the menu button, and choose “Delete Template Set” from the Template menu. Template Layout All templates are similar in nature: • Each template has a Clear button which sets the data back to its default values.
Using the Templates third, or evaluate, column contains "?" buttons next to variables that can be calculated. To compute a value, tap the "?" button next to the variable to be computed. Some templates offer multiple methods of looking at the same variable. In such cases, a box appears around the variable's label. For example, in the Tip template (shown above), the tip can either be an amount ("Tip$"), a percentage selected from a pop-up list ("Tip"), or a manually entered percentage ("Tip%").
Using the Templates available to the input calculator through the “func” function list button. Entries made in the main calculator are separate from the input screen except for the memory, which provides a simple way of sharing values between the calculator and templates. To store the value in the input screen back to the template tap the “9” or save button. To return to the template without saving, tap the “x” or cancel button. Date Selector The date selector is used to enter dates.
Using the Templates template itself. The "actual" day count method counts the actual number of days in a month (even allowing for leap years) and the total number of days in a year. The 30/360 method treats all months as though they have 30 days and years as though they have 360 days. The actual/360 method counts the actual number of days in a month, but treats years as though they have 360 days.
Using the Templates from the Variable pop-up list. Selecting “Set All” will set all the variables to the current variable’s preferences. • Variable: the variable to set. • Dec Setting: sets the displayed decimal places - float mode displays all available decimal places, 0-11 sets the decimal places to that number of places. • Disp. Mode: numbers can be displayed in normal mode, scientific notation or engineering notation. See Calculator Settings section for details.
Business Computations Business Computations A series of business computations exist. Included are templates to perform percent change, profit margin, discount, markup, sales tax and tip computations. Discount This template performs discount computations: • Price: current price. • Sales Price: sales price. • Discount%: percentage discount. For example, a 30% discount would be entered as “30”. Markup This template performs markup computations: • Method: computation based on price or cost.
Business Computations • Old: the old value. • New: the new value. • Change%: the percentage changed per period. 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. Percent change set to one period and markup as a percentage of cost are identical computations. Profit Margin This template performs profit margin computations: • Cost: the cost to manufacture or purchase.
Business Computations • After Tax: after tax amount. Tip The tip template computes tip, total bills, and performs bill-splitting functions. • Bill: the bill amount before tip. • Tip/Tip%/Tip$: "Tip" allows a percentage to be chosen from the pop-up list. "Tip%" allows a tip percentage to be manually entered. "Tip$" allows a tip amount to be shown or entered. • Total: the total amount including the tip. • #People: the number of people paying for the meal.
Business Computations Old 45,000,000 New 115,000,000 Periods 4 Compute the percent change by selecting “?” on the Change% line. Sales have increased 26.44% per year, comparing favorably to the 20% industry pace. Profit Margin To perform this computation, choose Profit Margin from the template menu on the main screen. Your division contributes $724,500,000 in revenue. The costs associated with revenue are $580,000,000.
Business Computations Discount To perform this computation, choose Discount from the template menu on the main screen. The coupon is for 10% off the original cost. What is the discounted price if the cost is $9.99? Variable Enter Clear… Price 9.99 Discount% 10 Comments Sets the display to its default values Compute the price by selecting “?” on the same line. The sales price is $8.99. Tip Calculation 1 To perform this computation, choose Tip from the template menu on the main screen.
Calendar Calendar Calendar computations include both date and time computations. Date Calculations Dates can be computed using an actual calendar year, the 30/360, actual/360 or actual/365 day-count method. • Method: the day-count method. See the section on Template Preferences under Template & Variable Settings. • Date 1: the date to compute from. • Date 2: the date to compute to. • Difference: the difference in number of days.
Calendar The bottom section performs time addition calculations: • Time: starting time. • HH.MMSS/HrsFrac: time duration. "HH.MMSS" displays time in hour, minute, second format (4hrs, 7mins, 30sec would display as 4.0730). "Hrs.Frac" displays time as a fraction of an hour. • Sum: the end time. Examples Date Go to the Calendar – Date template to compute this problem. Vacation begins on October 13, 2002. Today is August 18, 2002.
Calendar Make sure Diff Hrs is showing instead of Diff H.MM. Compute the difference by selecting “?” on the same line. This project took 4.5833 hours (4 hours, 35 minutes). To finish the calculation, select the Diff Hrs value and multiply by 30. You should bill $137.50 for your work. Time Sum Go to the Calendar – Time template to compute this problem. If you start driving at 3:15 pm and the trip will take 5hrs, 45mins, what time will you arrive? Variable Enter Tap the Clear… button Time 3:15 pm H.
Calculation Log Calculation Log The calculation log displays computations as they are entered, which makes double-checking easier. Access the calculation log by choosing its option from the powerOne button in the main calculator. To scroll the list, choose the scroll arrows or scroll buttons.
