What Is a Subscript in Math?
A subscript is a character or string that is smaller than the preceding text and sits at or below the baseline. When used in the context "Fn," it refers to a function evaluated for the value "n." The text n-1 and n-2 are also subscripts that define previous values of "n" in the sequence.

Also asked, what is a subscript number?

A subscript is a character, usually a letter or number, that's printed slightly below and to the side of another character. Subscripts are commonly used in chemical formulas. A scientist would write the formula for water, H2O, so that the 2 appears lower and smaller than the letters on either side of it.

Likewise, what is an example of a subscript? Subscript is the text which a small letter/number is written after a particular letter/number. It hangs below its letter or number. It is used when writing chemical compounds. An example of subscript is N2. Superscript is the small letter / number above a particular letter / number.

Just so, what does a subscript 0 mean?

Commonly, variables with a zero in the subscript are referred to as the variable name followed by "naught" (e.g. v0 would be read, "v-naught"). Also in mathematics and computing, a subscript can be used to represent the radix, or base, of a written number, especially where multiple bases are used alongside each other.

What is a subscript variable?

A subscripted variable is the combination of the array name and a subscript. You can use a subscripted variable anyplace an ordinary variable can go. For example, in the above program a value was copied from a subscripted variable to an ordinary variable: LET HOTDATE$ = DATE$(5)

How do you type a superscript?

For superscript, simply press Ctrl + Shift + + (press and hold Ctrl and Shift, then press +). For subscript, press CTRL + = (press and hold Ctrl, then press =). Pressing the respective shortcut again will get you back to normal text.

What are coefficients?

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. For example, if y is considered as a parameter in the above expression, the coefficient of x is −3y, and the constant coefficient is 1.5 + y.
