The panel on the left will hold the calculator buttons and display , and the panel on the right will show a record of the arithmetic operations performed by the user 控件分成两个面板。左侧的面板包含计算器按钮和显示器，右侧面板显示用户执行的算术运算的记录。
A functional unit that can perform substantial computation , including numerous arithmetic operations or logic operations , without intervention by ahuman operator during a run 能执行大量计算,包括许多算术运算和逻辑运算,而在运行期间无需操作员干预的一种操作装置。
An abnormal condition detected by the hardware . examples are : attempts to execute a privileged instruction and arithmetic traps such as overflow , underflow , and divide by zero 一种由硬件检测到的非正常状态。例如:企图执行一条特权指令和诸如上溢出、下溢出与除0等的算术运算陷井。
Computer is a functional unit that can perform substantial computation , including numerous arithmetic operations or logic operations , without intervention by human operator during a run 计算机是能实现基本运算的一种功能设备。其中包括大量的算术运算或逻辑运算，在运行期间无需操作员去干预。
Property of the new instance to a system - supplied message that describes the error , such as " the arithmetic operation is not allowed . " this message takes into account the current system culture 属性初始化为系统提供的、描述错误的消息，如“不允许算术运算。 ” 。此消息将考虑当前系统区域性。
These procedures involves breaking the calculation down into a sequence of arithmetic operations and a series of instructions , and demand the computer to carry out the required operations in the correct order 这些步骤包括把这一计算分解成一串算术运算和一系列的指令，要求计算机按所要求的次序进行运算。
One or more digits , produced in connection with an arithmetic operation on one digit place of two or more numerals in positional notation , that are forwarded to another digit place for processing there 以按位记数法表示的两个或多个数在一个数字位上进行算术运算所产生的一位或多位数，该数被传送到另一个位上以进行处理。
Think of it this way : if you had three variables , two of which held numbers while the third held a name , you could perform arithmetic using the first two , but you can t perform arithmetic on the name 可以这样来考虑：假定您有三个变量，前两个保存数值，第三个保存名称，那么，您可以使用前两个变量执行算术运算，但不能对名称执行算术运算。
