Basic calculation

Before performing the following calculation, check to see that your
calculator is in decimal base and floating point display.

Mixed arithmetic calculation

1 + 2 x 3 = ? 1 [ + ] 2 [ x ] 3 [ = ]
÷
– 3.5 + 8 2 = ? 3.5 [ +/– ] [ + ] 8 [

Parentheses calculations

Operation inside parentheses are always executed first. You can use
up to 15 levels of parentheses in a single calculation. When the first
parenthesis is opened, the " ( ) " indicator appears and remains in the
display until the last parenthesis is closed.
( 5 – 2 x 1.5 ) x 3 [ ( ] 5 [–] 2 [ x ] 1.5 [ ) ] [ x ]
+ 0.8 x (– 4 ) = ? 3 [ + ] 0.8 [ x ] 4 [ +/– ] [ = ]
2 x { 7 + 6 x ( 5 + 2 [ x ] [ ( ] 7 [ + ] 6 [ x ] [ ( ]
4 ) } = ? 5 [ + ] 4 [ = ]
(Note) : It is unnecessary to press the [ ) ] key before the [ = ] key.

Constant calculation

The calculator enables you to repeat the last number entered or the
last operation executed by pressing [ = ] key.
Repeating the last number
3 [ x ] [ = ]
3 x 3 = ?
3 x 3 x 3 = ? [ = ]
3 x 3 x 3 x 3 = ?
[ = ]
Repeating the arithmetic operation
321 [ + ] 357 [ = ]
321 + 357 = ?
654 + 357 = ?
654 [ = ]
579 [–] 159 [ = ]
579 – 159 = ?
456 – 159 = ?
456 [ = ]
3 [ x ] 6 [ x ] 45 [ = ]
18 x 45 = ?
18 x 23 = ?
23 [ = ]
2
18 x (0.5 x 10 )
= ?
