For example
Number1		Operate1	Number2		Operate2	result

1. Hex arithmetic ("H": Hex):
123A		*		7		=		7F96(Hex)

123		+				D/H		NOP

4. Arithmetic will overflow if absolute value is more than 7FFFFFFF,
and then a mark of "E" will be displayed on the screen.
7FFFFFFF	+		123		=		E(overflow) 80000122

5. Divisor can't be 0:
15		/		0		=		E(overflow) 0	

6. Backspace:
 a. 1234	->						123
 b. 1234	+		567		->		56
 c. 2		+				->		NOP
 d. 2		+		3		=		5
		->						NOP
