cursor donde el error está. Presionar [ ] o [ ] para mover el cursor y luego para darle una entrada correcta. Usted también puede borrar un error presionando [ CL ] y luego re-entrando los valores y la expresión desde el principio. Vea Ejemplo 3.

„Función de memoria

zPresionar [ M+ ] para adicionar un resultado a la memoria corriente. Presiona [ 2nd ] [ M– ] para restar el valor de la memoria corriente. Para revocar el valor en la memoria corriente, presionar [ MRC ]. Para borrar la memoria corriente, presiona [ MRC ] dos veces. Vea Ejemplo 4.

zLa calculadora tiene diez variables de memoria para el uso repetido : A, B, C, X, Y, M, X1, X2, PROG1 y PROG2. Usted puede guardar un número real en las variables A, B, C, X, Y, M, X1, X2 y dos expresiónes en PROG1 y PROG2. Vea Ejemplo 5.

*[ P/V RCL ] rellama todas las variables.

*[ SAVE ] le permite almacenar valores a las variables.

*[ 2nd ] [ RECALL ] rellama el valor de la variable.

*[ 2nd ] [ CL-VAR ] borra todas las variables excepto PROG1, PROG2.

*[ 2nd ] [ CL-PROG ] borra los contenidos de PROG1, PROG2.

(Nota) : Además de presionar tecla [ SAVE ] para almacenar un valor, usted también puede asignar valores a la variable de memoria M con [ M+ ] o [ 2nd ] [ M– ]. Sin embargo, cualquier cosa actualmente almacenado en la variable M se anulará y se lo reemplazará con el valor recientemente asignado.

„Orden de operaciones

Cada cálculo es ejecutado en el orden siguiente de prioridad :

1)Expresión dentro de los paréntesis.

2)Transformación de las coordenadas, y funciones Tipo B que se
