Help Manual:

// means a line comment or annotation.

A=2

B=3

C=A+B

Click Run, the screen shows:

C=5

If the line C=A+B is annotated ,

A=2

B=3

//C=A+B

Click Run, the screen shows:

B=3

- Variable Naming Rules:

Start with letters, and not involving keywords.

A, A1, B25, HAT (right)

PRINT1, COS (wrong)

- The Usage of PRINT:

A=10+5

B=10/5

PRITN A,B

Click Run, the screen shows:

A=15

B=2

Default variable name is RESULT , e.g.

16+5*6

Click Run, the screen shows:

RESULT=46

- Combination & Arrangement:

C(n,k) = n!/(k!(n-k)!)

A(n,k) = n!/(n-k)!

- Complex Number

When there is i or on the screen, it automatically enters Complex Number Calculation Mode.

e.g.
X=3+4i or X=553.1

9 functions are available for the Mode.

SIN(X), COS(X), TAN(X)

COT(X), SINH(X), COSH(X)

SQRT(X), ABS(X), CONJUGATE(X)

- Integral

INTEGRAL X,2,4

Default precision is 300 times of calculations.
It can be more accurate, e.g.
500 times.

INTEGRAL X,2,4,500

- Graphics

PLOT SIN(X)

PLOT X

Default length = 10, width = 10.
Specify the lenght = 20, width = 5.
Then we have,

PLOT X,20,5

Default dense is 150 points.
It also can be customized, e.g.
200 points.

PLOT X,20,5,200,
