Basic Calculation
(Including Parenthesis Calculations)
÷
(Ex.) : – 3.5 + 8 2 = 0.5
÷
3.5 [ +/–] [ + ] 8 [ ] 2 [ = ]
(Ex.) : ( 5 – 2 x 1.5 ) x 3 + 0.8 x ( – 4 ) = ?
[ ( ] 5 [ – ] 2 [ x ] 1.5 [ ) ] [ x ] 3 [ + ] 0.8 [ x ]
4 [ +/ – ] [ = ]
(Ex.) : 2 x [ 7 + 6 x ( 5 + 4 ) ] = 122
2 [ x ] [ ( ] 7 [ + ] 6 [ x ] [ ( ] 5 [ + ] 4 [ = ]
(Note) : It is unnecessary to press the [ ) ] key before the [ = ] key.
