n.加数
As the addend key in the parameter set state. 在参数设定状态下,作加数键。
A quantity to which the addend is added. 被加数被加上加数的量
One addend adds one number. The other addend subtracts the same number. The sums are the same. 小结：一个加数增加几，另一个加数减少几，增加和减少的数相等，它们的和仍是10。
Thus, the augend and addend must each be small enough to fit within one memory location. 由此可见，加数和被加数都应足够小，以便能够适合地装入一个存储单元。
