SAMPLE CALCULATIONS:

Square root calculation:		Constant calculation:
36 + 13 = 7		4 × 3 = 12 4 × 5 = 20
36+13=	7	4 × 3= 5=	1220
Percentage calculation:
30 × 5% = 1.5		6 ÷ 2 = 3 8 ÷ 2 = 4
30× 5%	1.5	6+2= 8=	34
Chain calculation:		Memory calculation:
[(6+4)× 2-8] ÷ 5 = 2.4		(5 × 0.25) + (6 × 0.75) - (2 × 0.15) = 5.45
6+4× 2 -8+5=	2.4	5×·25M^2	MEMORY 1.25
		6×·75M^2	MEMORY 4.5
		2×·15M	MEMORY 0.3
Power calculation:		MRC	MEMORY 5.45
2^4 = 16		MRC	5.45
2×= = =	16
