以下是翻译好的内容：
这些术语中每个单词的标准词典定义应该能让您大部分理解。
它是mutative，因为它会改变（更改/修改/等等）变量sum以得出结果。
它是accumulation，因为数字逐渐相加形成总和。
英文:
The standard dictionary definitions for each of those words in the term should get you most of the way to understanding.
It's mutative because it mutates (changes/alters/ etc) the variable sum to arrive at the result
It's an accumulation because the numbers are added to form the sum gradually
