not shown in the calculation examples.)
• 当按下 , , , 或 时，“=”符号会显示在显示屏上。（该符号不出现在计算示例
中。）
CALCULATING TAX / 计算税率
• To perform a tax calculation, first it is absolutely necessary to set and check the tax rate. (The initial
tax rate is 0.)
A tax rate can be set (or changed) with a number containing up to four digits. (Decimal point is not
regarded as a digit.)
The set tax rate is retained until it is changed. However, the set tax rate may be changed or lost if the
battery is consumed largely.
• 要执行税率计算，首先当然需要设置和检查税率。（初始税率设置为 0）。
税率可以使用最多4位数字设置（或更改）。（小数点不作为数字。）
设置的税率会一直保留到下次更改。但是，如果电池基本耗尽，设置税率也会更改或丢失。

• 确认税率。（0%）

(1) • Perform two calculations using $84
and $52.5, both of which already
include tax. (tax rate: 5%)
Calculate the tax on the total and
the total without tax.
• 对 $84 和 $52.5 执行计算，两者均
已含税。（税率：5%）
计算税费总额和去税总额。
