E-28To determine the bitwise complement of 10102 (Not(10102))A13(BASE)5(Not) 1010 )= 1111111111110101To negate (take the two’s complement) of 1011012 (Neg(1011012 ))A13(BASE)6(Neg) 101101 )= 1111111111010011Note: In the case of a negative binary, octal or hexadecimal value, thecalculator converts the value to binary, takes the two’s complement, andthen 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 simultaneouslinear equations with two or three unknowns, quadratic equations, and cubicequations.1. Press N5(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 twounknowns 1(a n X + bn Y = c n )Simultaneous linear equations withthree unknowns 2(a n X + bn Y + c n Z = dn)Quadratic equation 3(aX 2 + bX + c = 0)Cubic equation 4(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 3 in step 2, and then inputthe following for the coefficients (a = 2, b = 1, c = –3): 2=1 =-3 =.• To change a coefficient value you already have input, move the cursorto the appropriate cell, input the new value, and then press =.• Pressing A will clear all of the coefficients to zero.Important: The following operations are not supported by the CoefficientEditor: m, 1m(M–), 1t(STO). Pol, Rec, and multi-statementsalso 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 anothersolution. Pressing = while the final solution is displayed will return tothe Coefficient Editor.• You can scroll between the solutions using the c and f keys.• To return to the Coefficient Editor while any solution is displayed, pressA.Note: • Even if Natural Display is selected, the solutions of simultaneouslinear equations are not displayed using any form that includes '. • Valuescannot be converted to engineering notation on the solution screen.Changing the Current Equation Type SettingPress N5(EQN) and then select an equation type from the menu thatappears. Changing the equation type causes the values of all CoefficientEditor coefficients to change to zero.
