(Including Parenthesis Calculations) 

(Ex.) : – 3.5 + 8 

÷

 2 = 0.5

3.5 [ +/–] [ + ] 8 [ 

÷

 ] 2 [ = ] 

DEG 

 0.5

(Ex.) : ( 5 – 2 x 1.5 ) x 3 + 0.8 x ( – 4 ) = ? 

[ ( ] 5 [ – ] 2 [ x ] 1.5 [ ) ] [ x ] 3 [ + ] 0.8 [ x ] 

4 [ +/ – ] [ = ] 

DEG 

 2.8

 (Ex.) : 2 x [ 7 + 6 x ( 5 + 4 ) ] = 122 

2 [ x ] [ ( ] 7 [ + ] 6 [ x ] [ ( ] 5 [ + ] 4 [ = ] 

DEG 

 122.

(Note) : It is unnecessary to press the [ ) ] key before the [ = ] key.
