Solar/mercury batteries used mathematical natural display, intuitive cropping into the order, built-in scientific constants, differential/integral, regression calculations, hyperbolic and inverse hyperbolic.

Mathematical nature show:

The semicolon, the square root of the displayed on the input sequence and textbooks, calculators have a more intuitive operating environment.

List of statistical data editing functions:

Use of statistical information in a simple list format, type, can be used in the statistical calculation model.

Clear display:

Clear display, score, logarithm, square root formula and symbol and displayed the same textbooks, learning much easier.

Easier to operate a central operation key:

Using the central key, can be found in bottom and move around in the equation, change, and can be used to perform a calculation, compound modified again after repeated function, correction and repeat the operation is very convenient.

Tabular calculations:

In the equation f (x) equation can be shown on the x-value operations out of f (x) value, etc.

Intuitive input order:

Textbook program order input operations.

Basic function:

Triangle, inverse triangle, logarithmic/exponential, square root, square, cube root, Countdown, PI, and so on.

Memory protection features:

Fractions:

Time calculations:

60 carry 10 rounded up

2 carry 8 carry 16 hexadecimal calculations.

Logic calculations: standard deviation

Regression calculations

Permutations and combinations

Hyperbolic and inverse hyperbolic

Coordinates conversion

ENG conversion

Complex number calculations

Differential

Formula

Index display

Built-in scientific constants

Built in the speed of light, gravitational force fixed rate

Asia-Plus gas constant Jue Luo scientific constants, such as 40

Repeat function:

Call had ever performed a formula, modified during execution, and therefore replaces the values of double counting is easy.

Answers and memory:

Computers automatically memorizes the latest calculations, and calls for continued use in the next calculation

Error function:

The cursor automatically moves to the wrong location

Continuous Computing features:

EXE (or =) keys, numerical value of the speed-closed operation continues to perform the operation.

The percentage of
