ese número de 100000000000000000000000000000000 en la base de ese número presionando tecla [ NEG ] para bases non-decimales. Vea Ejemplo 60.

„Operaciones aritméticas básicas para bases

zLa unidad le permite que usted calcule en la base del número de otra manera que el decimal. La calculadora puede adicionar, restar, multiplicar, y dividir números binarios, octales, y hexadecimales. Vea Ejemplo 61.

„Operaciones lógicas

Operaciones lógicas son ejecutadas a través de productos lógicos (AND), negativo lógico (NAND), sumas lógicas (OR), sumas lógicas exclusivas (XOR), negación (NOT), y negación de sumas lógicas exclusivas (XNOR). Vea Ejemplo 62.

Mode 3 - CPLX

zModo complejo le permite de adicionar, restar, multiplicar, y dividir los números complejos. Vea el Ejemplo 63. Los resultados de una operación compleja son mostradas como sigue:

Re

Valor Real

Im

Valor Imaginario

ab

Valor Absoluto

ar

Valor del argumento

Mode 4 - VLE

Modo de ecuaciones de variables lineales (VLE) puede resolver una serie de ecuaciones simultáneas con dos números incógnitos como sigue :

a x + b y = c

d x + e y = f, donde x y son incógnitos.

zEn modo VLE, usted apenas entra cada coeficiente (a, b, c, d, e, f) en el orden correcto, y la calculadora resuelve automáticamente para x, y. Vea Ejemplo 64.

Mode 5 - QE

Modo de ecuaciones cuadráticas (QE) puede resolver ecuaciones como sigue :

a x 2 + b x + c = 0, donde x son desconocidos.

zEn modo QE, usted entra apenas cada coeficiente (a, b, c) en el orden correcto, y la calculadora resuelve automáticamente para todo los valores x. Vea Ejemplo 65.

S – 20
