To determine the bitwise complement of 10102 (Not(10102))

(BASE)(Not) 1010  1111111111110101

To negate (take the two’s complement) of 1011012 (Neg(1011012)) (BASE)(Neg) 101101  1111111111010011

Note: In the case of a negative binary, octal or hexadecimal value, the calculator converts the value to binary, takes the two’s complement, and then converts back to the original number base. For decimal (base-10) values, the calculator merely adds a minus sign.

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:

Press this key:

Simultaneous linear equations with two

(anX + bnY = cn)

unknowns

 

 

Simultaneous linear equations with

(anX + bnY + cnZ = dn)

three unknowns

 

 

Quadratic equation

(aX2

+ bX + c = 0)

Cubic equation

(aX3

+ bX2 + cX + d = 0)

3.Use the Coefficient Editor that appears to input coefficient values.

•To solve 2x2 + x – 3 = 0, for example, press in step 2, and then input the following for the coefficients (a = 2, b = 1, c = –3): 21 3.

•To change a coefficient value you already have input, move the cursor to the appropriate cell, input the new value, and then press .

•Pressing will clear all of the coefficients to zero.

Important: The following operations are not supported by the Coefficient

Editor: 6, 6(M–), =(STO). Pol, Rec, and multi-statements also cannot be input with the Coefficient Editor.

4.After all the values are the way you want, press .

•This will display a solution. Each press of  will display another solution. Pressing while the final solution is displayed will return to the Coefficient Editor.

•You can scroll between the solutions using the A and D keys.

•To return to the Coefficient Editor while any solution is displayed, press

.

Note: • Even if Natural Display is selected, the solutions of simultaneous linear equations are not displayed using any form that includes . • Values cannot be converted to engineering notation on the solution screen.

Changing the Current Equation Type Setting

Press (EQN) and then select an equation type from the menu that appears. Changing the equation type causes the values of all Coefficient Editor coefficients to change to zero.
