The Casio fx-570ES PLUS is a non-programmable scientific calculator from Casio Computer Co., Ltd., part of the ES PLUS series. It features a Natural Textbook Display with a dot-matrix LCD, 417 built-in functions, multiple calculation modes including statistics, matrices, vectors, equations, and base-n arithmetic, and is powered by a single AAA (R03) battery. It is primarily designed for educational use and does not include graphing or programming capabilities.
This model has exactly the same functions as the Casio fx-991ES PLUS, differing only in power supply, dimensions, and weight. The fx-991ES PLUS uses a built-in large solar cell together with one LR44 battery, resulting in a smaller size and lighter weight. This model uses one AAA battery, resulting in a larger size and heavier weight.
History
edit- The predecessor of the fx-570ES PLUS, the fx-570ES, was released in the mid-2000s. This calculator was not very popular, while its sibling model, the fx-991ES, achieved better sales.
- The fx-570ES PLUS was released in the late 2000s with improved functionality, and the fx-570ES was gradually withdrawn from the market. However, to this day, the popularity of the fx-570ES PLUS still does not surpass that of the fx-991ES PLUS.
Calculation modes
edit- There are eight calculation modes: basic calculation (COMP), complex number calculation (CMPLX), statistical calculation (STAT), base-n calculation (BASE-N), equation calculation (EQN), matrix calculation (MATRIX), table generation using functions (TABLE), and vector calculation (VECTOR).
