Removing the Hard Case Before using the calculator, slide its hard case downwards to remove it, and then affix the hard case to the back of the calculator as shown in the illustration nearby. 12. Inputting Expressions and Values 4 × sin30 × (30 + 10 × 3) = 120 v 4 *s 30 *( 30 + 10 * 3 )= Note: · The memory area used for calculation input can hold 79 "steps". [. . . ] RanInt# (fx-82SX PLUS/220 PLUS only): For input of the function of the form RanInt#(a, b), which generates a random integer within the range of a to b. Configuring the Calculator Setup Pressing the , key more than once displays additional setup screens. 1Deg 2Rad 3Gra Specifies degrees, radians or grads as the angle unit for value input and calculation result display. Note: In this manual, the v symbol next to a sample operation indicates degrees. 1Fix 2Sci 3Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displayed calculation results. Calculation results are rounded off to the specified digit before being displayed. Example: 100 ÷ 7 = 14. 286 (Fix 3) Sci: The value you specify (from 1 to 10) controls the number of significant digits for displayed calculation results. Calculation results are rounded off to the specified digit before being displayed. Example: 1 ÷ 7 = 1. 4286 × 10­1 (Sci 5) Norm: Selecting one of the two available settings (Norm 1, Norm 2) determines the range in which results will be displayed in nonexponential format. Outside the specified range, results are displayed using exponential format.

The corresponding x-value (two values, x1 and x2, in the case of quadratic regression) also can be calculated for a value of y in the regression formula.
