“//” means a line comment or annotation.
"//"は注釈を意味しま‏す‎。

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:
変数の命名規則：
Start with letters, and not involving keywords.
A, A1, B25, HAT (right)
PRINT1, COS (wrong)

- The Usage of PRINT:
PRINTの使用法：

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)!
