首先是加减乘除。
在夏普计算器上，加号“+”、减号“-”、乘号“×”、除号“÷”通常都有专门的按键，使用起来非常方便。
例如，要计算12加上34，只需要按下“12”、“+”、“34”、“=”即可得到结果。
同样，要计算56减去23，只需要按下“56”、“-”、“23”、“=”即可得到结果。
乘法和除法的操作也是类似的，只需按下相应的按键即可完成计算。
其次是百分比。
在夏普计算器上，百分号“%”通常有专门的按键，用于计算百分比。
例如，要计算25%的50是多少，只需要按下“50”、“×”、“25”、“%”、“=”即可得到结果。
这个功能在商业计算和统计计算中经常会用到，非常实用。
除了基本的加减乘除和百分比计算，夏普计算器还具有许多其他实用的功能。
例如，平方根计算。
在夏普计算器上，通常有一个平方根“√”的按键，用于计算一个数的平方根。
例如，要计算81的平方根，只需要按下“81”、“√”即可得到结果。
这个功能在数学计算和工程计算中经常会用到。
此外，夏普计算器还具有倒数、正弦、余弦、正切等高级数学函数的计算功能，以及科学计算、统计计算、金融计算等高级功能。
这些功能在专业领域的工作中经常会用到，可以大大提高工作效率。
除了基本的计算功能，夏普计算器还具有一些实用的操作技巧。
例如，夏普计算器通常具有清零“C”和全部清除“AC”两个按键，用于清除输入的数据。

·如果一个表达式的数字位数大于9，假/真分数会转换成十进制数并显示。
混合分数的情况下，最大可显示位数是8(包括整数)。
·如果一个分数的分母位数由于使用π而大于3位，结果将会转换成十进制数并显示。
行编辑输入和显示在行模式下，可以一行一行的输入并显示算式。
注意：·在屏幕上可以一次查看三行的文本。
·如果算式的长度超过三行，计算后其一部分可能会隐藏。
如果你想查看算式的其余部分，按下或回到编辑屏幕。
·在行模式下，计算结果以十进制显示。
编辑算式得到答案后，按下回到算式的末尾，按下回到算式的开头。
按下，，或移动光标。
按下或使光标跳到算式的开头或末尾。
例如，在书写模式下，可以用和使光标在分子和分母之间上下移动。
退格和删除键删除一个数字或函数，把光标移动到它的右侧，然后按下。
也可以通过按下直接删除光标处的数字或函数。

(，)·当在行模式下使用或时，用下面的方法输入数值：·logn(底数，数值)·abs数值随机数功能随机数功能有四种设置(当使用N-base功能时不能选择此项功能) 。
按连续产生随机数，按退出。
随机数伪随机数，按下可以产生从0到的三位有效数字。
注意：在书写模式下，结果将是分式或0。

按下和一个变量键会从存储器中呼出一个数值。
在等式中命名一个变量，按下和一个变量键。
独立存储器(M)除暂时存储器的所有特点外，还可以从当前的存储数值中加上或减去一个数值。
按下可以清除独立存储器(M)。
最终结果存储器(ANS)计算结果可以通过按下或任何其它的运算结束指令自动的存储在最终结果存储器中。
