20021201 Using Main Application Modes The Main application has a number of different modes that control how calculation results are displayed, as well as other factors.
20021201 Accessing ClassPad Application Windows from the Main Application T apping the down arrow button on the toolbar displays a palette of 10 icons that you can use to access certain windows of other ClassPad applications.
20021201 Accessing the Main Application Window from Another ClassPad Application Almost all of the ClassPad applications allow you to access the Main application window by tapping O and then [Main]. In the Statistics application and some other applications, you can also access the Main application window by tapping the ~ button.
20021201 2-2-1 Basic Calculations 2-2 Basic Calculations This section explains how to perform basic mathematical operations in the Main application. Arithmetic Calculations and Parentheses Calculations •Y ou can perform arithmetic calculations by inputting expressions as they are written.
20021201 Using the e Key Use the e key to input exponential values. Y ou can also input exponential values using the E key on the 9 and ) keyboards. Examples: 2.54 × 10 3 = 2540 c.fe e d w 1600 × 10 –4 = 0.16 bgaaE-e w Omitting the Multiplication Sign Y ou can omit the multiplication sign in any of the following cases.
20021201 Tip • The “ans” variable is a system variable. For details about system variables, see “1-7 V ariables and Folders”. • Since “ans” is a variable name, you can specify the “ans” variable by inputting [a][n][s] on the 0 (alphabet) keyboard, or by tapping the D key on the 9 or the ) keyboard.
20021201 Calculation Priority Sequence Y our ClassPad automatically perf or ms calculations in the following sequence. 1 Commands with parentheses (sin(, diff(, etc.) 2 Factorials ( x ! ), degree specifications ( o , r ), percents (%) 3 Powers 4 π , memory , and variable m ultiplication operations that omit the multiplication sign (2 π , 5A, etc.
20021201 Calculation Modes The Main application has a number of different modes, as described under “Using Main Application Modes” on page 2-1-4. The display format of calculation results depends on the currently selected Main application mode.
20021201 u Using the u Button to T oggle between the Standard Mode and Decimal Mode Y ou can tap u to toggle a displayed v alue between Standard mode and Decimal mode format. Note that tapping u toggles the format of a displayed value. It does not change the current Standard mode/Decimal mode setting.
20021201 k Complex Mode and Real Mode The Complex mode is for complex number calculations, while the Real mode is limited to calculations within the range of real numbers. Performing a calculation in the Real mode that produces a result that is outside the range of real numbers causes an error (Non-Real Result error).
20021201 2-3 Using the Calculation History The Main application work area calculation history can contain up to 30 expression/result pairs. Y ou can look up a previous calculation, edit, and then re-calculate it, if you want. V iewing Calculation History Contents Use the scroll bar or scroll buttons to scroll the work area window up and down.
20021201 Re-calculating an Expression Y ou can edit a calculation expression in the calculation history and then re-calculate the resulting expression. T apping w re-calculates the expression where the cursor is currently located, and also re-calculates all of the expressions below the current cursor location.
