x! = n x (n–1) x (n–2) x (n–3) x .....x 2 x 1
(3) [OFF] : Power off key.
(4) [SHIFT] : This is the key for specifying the second function. When this key is pressed, the special display “SHIFT” lights. When this key press twice continuously, the second function mode releas.
(5) [DRG]: a. Pressing this key will change the mode of angle unit
sequentially DEG RAD GRAD and display it on LCD.
b.Pressing this key after [SHIFT] key shall change the mode of angle and shall convert the displayed data.
DEG → RAD : RAD = DEG x π/180
RAD → GRAD : GRAD = RAD x 200/π
GRAD → DEG : DEG = GRAD x 180/200
(6) [0] ~ [9] : Press these keys in their logical sequence to enter numbers.
(7)[RND] : a. Use to set the decimal point when entering numbers.
b.When press as the first number, it is regarded as [0] and [ • ] keys are pressed.
c.Random as a second function.
Pressing this key shall display the random number. The range of random number is 0.000~0.999.
(8)[+/–] : a. In setting data in the mantissa section, this key reverse
code in the mantissa section similarly for exponent section, it reverse code in the exponent section.
b.For the operation result, this key reverse code in the mantissa section.
(9)[+], [–], [x], [ ÷ ], [ ( ], [ ) ]
a. When the key operations are performed by these keys according to a numerical expression, a result of operation is obtained according to mathematical priorities. Priorities discriminated are:
1)1-variable function.
2) Expression in "( )"; (The most inner expression has priority in case of multiple parenthesis)
3)xy, y x
4)x, ÷

b.Whenever the key is operated, the calculator discriminates the above priorities and holds the data and operation keys pending as required.
This pending action is possible up to 6 times, and 15 levels or more pending become error.
c.[ ( ] key is accepted only immediately after [CE], [+], [–], [x], [÷], [xy], [ y x ], [=], [ ( ] keys can not accepted in all other cases.
When this key is accepted, the displayed data is cleared to 0. When [ ( ] key is first accepted, the special display “( )” illuminates.
When a parenthesis expression is completed [ ) ] and [=] key or
When it is cleared by the [ON/C] key, etc. or when errors are generated, the special display “( )” goes out.
d.If it is within the allowable range of pending, [ ( ] can be input into any place in an expression as many times as desired. However, if the key is pressed continuously 16 times or more, it becomes error.
e.From a viewpoint of numerical expression when the corresponding “ ) ” key is not pressed, the operation is not executed even if the “ ( ” key is pressed. On the other hand, When the “ ( ” key is pressed and the “ = ” key is the pressed without pressing the corresponding “ ) ” key, the operation is also completed according to the priority.
(10)[X→M], [MR], [M+] Memory calculation
a.The memory register “M” used by these keys is a completely independent single memory.
b.Display data is added to “M” (memory register) by [M+] key. If data overflows at this time, the proceeding data is hold.
c.Display data is stored in “M” by [X→M] key.
d.Contents of “M” is displayed by [MR] key.
e.When any data except for 0 is stored in “M”, the special display
“M” illuminates.
(11)[EXP] : 1. Exponent select key.
2.This key display a rounded value : 3.141592654.

Because there is automatic priority of operations Logic the calculations, may be performed as expressed in the equation. (Calculation order of priority).
1.Function calculations.
2.Calculation in ( ).
3.Power and Root calculation.
4.Multiplication and division.
5.Addition and subtraction.

When execution starts with high priority calculations it is necessary to save low priority calculation, and for that reason there are 6 internal storage levels supplied.
These storage levels are also used in calculations involving parenthesis, therefore as long as priority operations involving parenthesis do not exceed 15 levels the calculations may be performed as they appear in the equation.

4. Calculations with parenthesis.
Parenthesis are used when it is desired to perform calculations in a first priority that usually followed for the +, –, x, ÷, xy, y x , operations.
In other words the “(” “)” force those prior operations it to be pending until the calculation inside the parenthesis are performed.
Parenthesis may be used in a chained calculation as long as the total of levels ending due to the automatic priority Logic and parenthesis does not exceed 15.

EL TECLADO Y CONTROLES OPERACIONALES
SD
(1) [ON/C] : 1. Enciende y borra una condición de error.
2. Abre y borra el modo de estadística.
-S2-
SR135_Spanish_090326.rtf SIZE:140x75mm SCALE 2:1 2009/3/26
x!
(2) [CE] : 1. Borra la tecla digitada.
2. Función factorial (x!).
x! = n x (n–1) x (n–2) x (n–3) x .....x 2 x 1
(3) [OFF] : Tecla de apagado.
(4) [SHIFT] : Esta es la tecla especificadora de la función secundaria.
Cuando se presiona esta tecla, un mensaje “SHIFT” aparece sobre la pantalla. Cuando se presiona dos veces seguidas, el modo función secundaria se desactiva.
(5) [DRG]: a. Esta tecla cambiará el modo de unidad de ángulo
secüencialmente DEG RAD GRAD y indicará sobre la pantalla LCD.
b.Presionando esta tecla después de la tecla [SHIFT] cambiase el modo de ángulo y convierte el dato sobre la pantalla.
DEG → RAD : RAD = DEG x π/180
RAD → GRAD : GRAD = RAD x 200/π GRAD → DEG : DEG = GRAD x 180/200
(6)[0] ~ [9] : Digitar estas teclas en su secuencia lógica para entrar
los datos.
(7) [RND] : a. Usado para definir el punto decimal durante la entrada de números.
b.Presionándola como primero número, se asumen como presionadas las teclas [0] y [ • ].
c.Aleatorio como segunda función.
Digitando esta tecla mostrará el número aleatorio. El intervalo de números aleatorios es 0.000~0.999.
(8) [+/–] : a. Entrando el dato en la sección de mantisa, esta tecla invierte el código del mismo modo como en la sección exponencial, ella invierte el código en la sección exponencial.
b.Para el resultado de la operación, esta tecla invierte el código en la sección de mantisas.
(9)[+], [–], [x], [ ÷ ], [ ( ], [ ) ]
a. Cuando las operaciones principales son ejecutadas por estas teclas según una expresión numérica, se obtiene un resultado de operación según las prioridades matemáticas. Prioridades discriminadas son:
1)Función con 1 variable.
2)Expresión entre "( )"; (La expresión más interna tiene prioridad en caso de paréntesis múltiplos)
3)xy, y x
-S3-
SR135_Spanish_090326.rtf SIZE:140x75mm SCALE 2:1 2009/3/26
4)x, ÷
5)+, –
b.Siempre que se presiona la tecla, la calculadora discrimina las prioridades arriba y mantiene los datos y teclas de operación pendientes si necesario.
Esta acción pendiente es posible hasta 6 veces, y 15 niveles porque muchas operaciones pendientes generan error.
c.La tecla [ ( ] es aceptada solamente después de las teclas [CE], [+], [–], [x], [÷], [xy], [ y x ], [=], [ ( ] no ser aceptadas en todos los otros casos. Cuando se acepta esta tecla, el dato mostrado es ajustado a cero. Cuando se acepta la tecla [ ( ] primero, la pantalla especial “( )” se ilumina.
Después de completada una expresión dentro de paréntesis tecleando [ ) ] y [=] o borrando con la tecla [ON/C], etc. o cuando los errores son generados, el mensaje especial “( )” desaparece.
d.Si está dentro del intervalo permitido de pendencia, [ ( ] se puede insertarse en cualquer lugar en una expresión cuantas veces desear. No obstante, si usar la tecla continuamente 16 veces o más, generará error.
e.Del punto de vista de la expresión numérica cuando no se presiona la tecla correspondiente “ ) ”, la operación no se ejecuta aún que la tecla “ ( ” es usada. Por otro lado, cuando la tecla “ ( ” es presionada y la tecla “ = ” es usada sin teclear la correspondiente “ ) ”, la operación también se completará según la prioridad.
(10)[X→M], [MR], [M+] Cálculo con memoria
a.El registrador de memoria “M” usado por estas teclas es una memoria completamente independiente.
b.El dato visualizado es sumado a “M” (registrador de memoria) a través de la tecla [M+]. Si ocurrir desbordamiento de datos, ellos serán mantenidos.
c.El dato visualizado será memorizado en “M” con las teclas
[X→M].
d.El contenido de “M” es mostrado con la tecla [MR].
e.Cuando se memoriza cualquier dato excepto 0 en “M”, el indicador especial “M” aparecerá sobre la pantalla.
(11)[EXP] : 1. Tecla de función exponencial.
2.Esta tecla muestra el valor redondeado: 3.141592654.
(12)[%=] : Cálculos
a.En cualquier modo de función aritmética usado, el número sobre la pantalla se convierte de porcentaje para decimal.
