This calculator is designed for Spain and Portugal market. I recently was able to obtain one from an auction site.
Introduction
Iberia is in reference to the Iberian Peninsula, which contains Spain and Continental Portugal. The fx-570SP X II Iberia is a calculator with all the keys, menus, functions, and prompts in Spanish.
Examples:
The trigonometric functions sin and sin ⁻¹ are labeled sen and Arcsen, respectively.
MCM is Minimo Comune Multiplo, also known as Least Common Multiple (LCM) in a lot of the world.
Likewise, MCD is Maximo Comune Divisor, also known as Greatest Common Divisor (GCD).
The calculator uses a decimal point as a separator between a number’s integer and fractional part.
The fx-570SP X II Iberia is based off the fx-570EX and the solar counterpart, the very popular fx-991EX Classwiz.
My review of the fx-991EX Classwiz from 2015: https://edspi31415.blogspot.com/2015/11/casio-fx-991ex-classwiz-review.html
There are several functions that are present of the fx-570SP X II Iberia that are not present in the fx-991EX Classwiz:
|_ ([ALPHA] [fraction bar template]): Euclidean Division. Returns the quotient, labeled C, and remainder, labeled R, from dividing two integers.
Example:
148 |_ 15 returns C=9, R=13
Π ([ALPHA] [ x ]): Product of a function f(x). In E Mat (Math IO), the product function is shown in a template form.
Example:
1^2/2 * 2^2/2 * 3^2/2 * 4^2/2 = Π(x^2/2, 1, 4) returns 36
MCM ([ALPHA] [ ÷ ]): Least Common Multiple
Example:
LCM(14, 21) → MCM(14, 21) returns 42
MCD ([ALPHA] [ × ]): Greatest Common Divisor
Example:
GCD(14, 21) → MCD(14, 21) returns 7
Simp ([ALPHA] [ ( ]): Manual simplification of fractions (when Simplificar - Manual is selected).
Repeating Bar ([ALPHA] [ √ ]): Allows to easily type repeating decimal patters.
Example:
1/3 can be written as 0.3 with a bar over the 3 (0.3333333333…).
Menu (Menú)
The modes of the available in the fx-570SP X II are same of the fx-991 EX Classwiz:
1: Calcular (Calculate)
2: Complejos (Complex Numbers)
3: Base-N (Base Conversions and Boolean Objects)
4: Matriz (Matrices)
5: Vector (Vector)
6: Estadística (Statistics)
7: Distribución (Distribution)
8: Hoja de cálculo (Spreadsheet – 1,700 byte capacity, 45 rows, 5 columns (A-E))
9: Tabla (Table – up two function f(x), g(x), can be graphed using a QR code)
A: Ecuación/Func (Equation Solver: Linear Systems and Polynomials)
B: Inecuación (Inequalities)
C: Verificar (Verify)
The fx-570SP X II can solve up to 4 x 4 linear systems and 4-degree polynomials.
Regressions included are:
y = a + b x
y = a + b x + c x²
y = a + b ln x
y = a e^(b x)
y = a b^x
y = a x^b
y = a + b/x
The fx-570SP X II is succeed by the fx-570SP CW (https://www.calculados.com/calculadoras/fx-570-sp-cw/#1683017979230-21cc574f-5c0e).
Final Thoughts
I am fluent in English (my first language) and speak some Spanish, so the fx-570SP X II is going to help practice mathematical terms in Spanish. I look forward to using this calculator.
Calculated Industries has a Spanish version of the Construction Master 5 named the Construction Master 5 En Espanol (https://www.calculated.com/prd201/Construction-Master-5-In-Spanish.html), I may want this for my collection.
