* 操作範例
1.一般計算操作
在執行計算前，先按
範例
1 x 2 x 3 = 6

5/4
A 0 2 3 F
2 x 3 = 6
2 + 4 + 6 = 12
1234 x 100
= 123,400
$14.90 + $0.35 – $1.45
+ $12.05 = $25.85
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 [%]

A 0 2 3 F
15 x 2 = 30
20 x 3 = 60
25 x 4 = 100
(total A = 190)
10 ÷ 5 = 2
4 x 2 = 8
(total B = 10)
A ÷ B = 19
3.常數計算
2 + 3 = 5

4.超出運算容量的消除
123456789012 x 100
= 12345678901200
5.稅率計算
200+TAX(25%)=250 200 [x] 25 [%] [+] [=]
