Before performing each calculation, press the [CE/C] key two times.
Example
2 x 3 = 6
6 + 4 + 7.5 = 17.5
3 – 6 – 4 = –7
5 x 3 ÷ 0.2 = 75
300 x 27% = 81
11.2
x 100% = 20%
56
300 + (300 x 40%) = 420 300 [+] 40 [%]
300 – (300 x 40%) = 180 300 [–] 40 [%]

= 2.125
135 x (12 + 14) = 3510
(12 + 14) ÷ 5 = 5.2
3.Constant Calculation
2 + 3 = 5
4 + 3 = 7
3 x 4 = 12
3 x 6 = 18
