单词	subscript
释义	Subscript A small letter or number placed slightly lower than the normal text. Examples: • the number 1 here: A1 (pronounced "A sub 1" or just "A 1") • the letter m here: xm (pronounced "x sub m" or just "x m") Often used when we have a list of values. Example: Average = (x1 + x2 + x3 + ... + xn)/n (Which means to add all x values, from 1 to n, then divide by n) Note: when the letter is up high it is a "superscript". See: Superscript
