Data values you register are normally stored in calculator memory. The message "Data Full" appears and you will not be able to input any more data if there is no memory left for data storage. If this happens, press the key to display the screen shown below.
The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here. Before performing a calculation, you first need to select the appropriate calculation mode. Use these settings to control how calculation results are displayed. Note that changing the Fix and Sci ...
Metric Conversion (fx-570MS/fx-991MS only) The calculator's built-in metric conversion commands make it simple to convert values from one unit to another. You can use the metric conversion commands in any calculation mode except for BASE. To input a metric conversion command into a calculation, press (CONV) and then input the two-digit number ...
Logarithmic Functions. Use the key to input log a b as log (a, b). Base 10 is the default setting if you do not input anything for a. The key also can be used for input, but only while Natural Display is selected. In this case, you must input a value for the base. Example 1: log 10 1000 = log 1000 = 3. Example 2: log 2 16 = 4.
Your calculator has nine preset variables named A, B, C, D, E, F, M, X, and Y. You can assign values to variables and use the variables in calculations.
Matrix Calculations (MATRIX) Use the MATRIX Mode to perform calculations involving matrices of up to 3 rows by 3 columns. To perform a matrix calculation, you first assign data to special matrix variables (MatA, MatB, MatC), and then use the variables in the calculation as shown in the example below. Example 1: To assign to MatA and to MatB ...
List Screen (Binomial PD, Binomial CD, Poisson PD, Poisson CD) Calculation Ranges, Number of Digits, and Precision. Permutation (nPr) and Combination (nCr) Example: To determine the number of permutations and combinations possible when selecting four people from a group of 10. Permutations: 10 (n P r) 4. 5040.
To change the calculator setup. 1. Press (SETUP) to display the setup menu. 2. Use and to scroll the setup menu, and then input the number displayed to the left of the item whose setting you want to change.
Statistical Calculations (STAT) To start a statistical calculation, perform the key operation (STAT) to enter the STAT Mode and then use the screen that appears to select the type of calculation you want to perform. Pressing any of the above keys ( to ) displays the Statistics Editor.
Function Calculations. Use the key to enter the COMP Mode when you want to perform function calculations. Note: Using functions can slow down a calculation, which may delay display of the result. Do not perform any subsequent operation while waiting for the calculation result to appear. To interrupt an ongoing calculation before its result ...
