Negative sign (–) Note: When squaring a negative value (such as –2), the value being squared must be enclosed in parentheses ( ). Since inputting appending a negative sign to the result. Always keep the priority sequence in mind, and enclose negative values in parentheses when required.
As shown above, the value or expression to the right of the cursor after (INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.) This capability can be used with the following functions: Overwrite Input Mode...
Important: • Depending on the type of calculation result that is on the display when you press the perform. • With certain calculation results, pressing the the displayed value. • You cannot switch from decimal form to mixed fraction form if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10.

Fix and Sci, the argument is rounded off to the specified digit. When Fix 3 is the display digits setting, for example, the result of 10 ÷ 3 is displayed as 3.333, while the calculator maintains a value of 3.33333333333333 (15 digits) internally for calculation. In the case of Rnd(10÷3) = 3.333 (with Fix 3), both the displayed value and the calculator’s internal value become...

Results: Mean: 3 To calculate the linear regression and logarithmic regression correlation coefficients for the following paired-variable data and determine the regression formula for the strongest correlation: ( ) = (20, 3150), (110, 7310), (200, 8800), (290, 9310). Specify Fix 3 (three decimal places) for results.
Equation Calculations (EQN) You can use the following procedure in the EQN Mode to solve simultaneous linear equations with two or three unknowns, quadratic equations, and cubic equations. 1. Press (EQN) to enter the EQN Mode. 2. On the menu that appears, select an equation type. To select this calculation type: Simultaneous linear equations with two unknowns...
