3. ARITHMETIC CALCULATIONS
Inverses, squares et exponents
[x
-1
]
[x
]
[x
]
[ ]
[SHIFT][10
x
]
Calculates the inverse amount of the value inputted
immediately before.
Calculates the square of the value input immediately
before.
Calculates the cubic form of the value input immediately
before.
Increases the value y (input before) to the power of x
(input after).
Calculates the power of 10 of the value inputted immedi-
ately after
E.g.:
8 [x
-1
] [=]
-> 8x
-1
| 0.125
3 [x
] [=]
-> 3x
| 9.
5 [x
] [=]
-> 5x
| 125.
5 [ ] 3 [=]
-> 5 3 | 125.
2 [ ] 5 [=]
-> 2 5 | 32.
[SHIFT][10
x
] [(-)] 3 [=] -> 10
-3
| 1.
-03
Roots
[√]
[SHIFT] [3√]
[SHIFT] [x√]
Calculates the square root of the value input immediately
after.
Calculates the cubic root of the value input immediately
after.
Calculates the Xth root of the number input immediately
after.
Using the previous examples:
[√] 9 [=]
-> √9
| 3.
[SHIFT] [3√]125 [=]
-> 3√125
| 5.
5 [SHIFT] [x√] 32 [=]
-> 5 x√ 32 | 2.
Fractions
[a b/c]
[SHIFT] [d/c]
Allows the input of a fraction with the numerator b and the
denominator c, and whole part a (optional).
Converts a decimal number into a whole number plus a
irreducible fraction, and vise-versa.
Converts decimal number into an irreducible fraction and
vise-versa.
