Many people are confused by how to express various things in math, or how to express them using a computer when certain formats are unavailable. This guide will attempt to help explain what various symbols mean.
Normally an exponent is written in “superscript”, that is a smaller version of the number going slightly above the top of the normal text.
Example: 53 62
On a computer using a word processor like Microsoft Word, you can make superscript by using the “font” specification (Check the individual help manual for more). When you cannot do this, however, you use a carrot d “^”.
Example: 5^3 6^2
In logarithms it is customary to write thebae in subscript, just like superscript but below the normal text as opposed to above it.
Example: Log35 Log26
You can get the subscript effect on a computer the same way as the superscript. When this isn’t available, though, it is customary to use brackets “[ ]” around the text to denote that it is indeed subscript.
Example: Log5, Log6
