2-2 Cálculos básicos
Esta sección explica cómo realizar operaciones matemáticas básicas en la aplicación
Principal.
Cálculos aritméticos y cálculos con paréntesis
•Puede realizar cálculos aritméticos introduciendo expresiones tal como se escriben. Todos
los cálculos de ejemplo mostrados a continuación se realizan usando el teclado virtual
9, a menos que se indique de otro modo.
•Para introducir un valor negativo, toque - o - antes de introducir el valor.
•Cuando un cálculo contiene operaciones artiméticas mixtas, se sigue el orden de las
operaciones (la multiplicación y división tienen prioridad sobre la suma y resta).
•Todos los cálculos de ejemplo se realizan en el modo decimal. Si se usara el modo
estándar, los resultados se verían en forma fraccionaria. Para más detalles acerca del
modo decimal y modo estándar, vea “Indicadores de modo de la barra de estado” en la
página 2-1-4.
Cálculo Operación de tecla
23 + 4.5 – 53 = –25.5 cd+e.f-fdw
56 × (–12) ÷ (–2.5) = 268.8 fg*(-bc)/(-c.f)w
(2 + 3) × 10

= 500 (c+d)Ecw
1 + 2 – 3 × 4 ÷ 5 + 6 = 6.6 b+c-d*e/f+gw
100 – (2 + 3) × 4 = 80 baa-(c+d)*ew
2 + 3 × (4 + 5) = 29 c+d*(e+f)w
(7 – 2) × (8 + 5) = 65 (h-c)*(i+f)w
g/(e*f)w o
) Ngce*fw
(1 + 2i) + (2 + 3i) = 3 + 5i (b+cP)+(c+dP)w
(2 + i) × (2 – i ) = 5 (c+P)*(c-P)w

Para más detalles acerca de la visualización de los cálculos y resultados en cada uno de los
modos anteriores, vea “Modos de cálculo” en la página 2-2-5.
Para alternar entre el formato decimal y fraccionario, toque u antes de presionar E.
