4. Calculations with parenthesis.

Parenthesis are used when it is desired to perform calculations in a first priority that usually followed for the +, –, x, ⎟, xy, y x , operations. In other words the “(” “)” force those prior operations it to be pending until the calculation inside the parenthesis are performed.

Parenthesis may be used in a chained calculation as long as the total of levels ending due to the automatic priority Logic and parenthesis does not exceed 15.

Example: 6+ [(5–3.6+5)x0.8–6] x3.2 =

Key Input		Display
[6] [+] [ ( ] [ ( ]		0.
[5] [–] [3] [ • ] [6] [+] [5]	[ ) ]	6.4
[x] [ • ] [8] [–] [6]	[ ) ]	– 0.88
[x] [3] [ • ] [2] [=]		3.184

5. Coordinate conversion:

(1)polar → rectangular Example:

	Key Input		Display
y	[2]	[a]	2.
	[60]	[b]	60.
	[SHIFT] [P→R]		1.
	x	[b]	1.732050808
