SuperScripts (Exponents)

& Subscripts

SuperScripts (Exponents):

To format one-or-more characters as a superscript or exponent, you need to surround the superscript text with a simple formatting code:

{$EXP the superscript} or {$exp the superscript}

for example, the text:

x{$exp 3} - 4x{$EXP 2} + 1 

will display as:

x³ - 4x² + 1

Note that the "EXP" (for EXPonent) is not case sensitive. There must be one-or-more blanks or an equals sign ("=") that will not display between the "EXP" and the superscript characters. Blank spaces following the first non-blank character in the superscript will display. Format code strings must begin and end in the same text string - they cannot span a line break.

---

Subscripts:

To format one-or-more characters as a subscript, you need to surround the subscript text with a simple formatting code:

{$SUB the subscript} or {$sub the subscript}

for example, the text:

x{$sub main} = H{$SUB 2}O

will display as:

x_main = H₂O

Note that the "SUB" is not case sensitive. There must be one-or-more blanks or an equals sign ("=") that will not display between the "SUB" and the subscript characters. Blank spaces following the first non-blank character in the subscript will display.

Example:

In the following text file, the first question uses "{$EXP 2}" in each answer choice to display "x²". The second question uses "{$SUB 1} to display "x₁".

\MC A C
(x + 2)(x - 3) =
A. x{$EXP 2} + x - 6
B. x{$EXP 2} - x + 6
C. x{$EXP 2} - x - 6
D. x{$EXP 2} - 5x - 1
E. x{$EXP 2} - 6
\TF A T
If the distance from the point (x{$SUB 1}, 0) to (3, 4) 
is 5, then x {$SUB 1} = 0.
