* 操作範例
1.一般計算操作
範例
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 – (300 x 40%) = 180

2.計憶計算的操作
(25 x 5) – (84 ÷ 3)
+ (68 + 17) = 38
(52 – 35) ÷ (14 – 3 x 2)
= 2.125
135 x (12 + 14) = 3510
(12 + 14) ÷ 5 = 5.2
3.常數計算
2 + 3 = 5
4 + 3 = 7
3 x 4 = 12
3 x 6 = 18
4.超出運算容量的消除
123456789012 x 10000
= 1'234.56789012 x 10
5.稅率計算
100+TAX(3%)
= 103
Tax sum = 3
3 = 稅值
103 = 含稅值
100–TAX(3%)
= 97.0873786407
Tax sum = 2.91262136
2.91262136 = 稅值
[M+] : 加法記憶鍵
[+ / –] : 正負號改變鍵
TAX : 稅收的量
–TAX : 不含稅的價格
+TAX : 含稅的價格
