### How to type math clearly

A common problem with typing math is that single-line type doesn't always mean the same thing as the nice formatting in your textbook. For instance, "1/3x" could mean either of the following:

. . . . .$\frac{1}{3x}$

. . . . .$\frac{1}{3}\,x$

If you would like to learn how to format using the LaTeX plug-in, as shown above, there are any number of good articles on the topic. This forum uses the "mimetex" package, which provides its own tutorial.

A quicker way to start, however, might be to learn the generally-accepted rules of web-safe math formatting. Note that the largest cause of confusion is the omission of grouping symbols. For instance, the two displays above can be typed very simply, respectively, as:

. . . . .1/(3x)

. . . . .(1/3)x

If you are working with something such as complex fractions, synthetic division, or matrices, where its nearly impossible to avoid the multi-line formatting, use "Code" tags (there's a button above the message-entry box) to "force" the characters to line up. For instance, long polynomial division might look like this:

Code: Select all
                       x^3 + 2x^2 -  x -  5        -----------------------------------x^2 - 2 )x^5 + 2x^4 - 3x^3 - 9x^2 + 2x + 10         x^5 + 2x^4 -  x^3 - 5x^2        -----------------------------------                    - 2x^3 - 4x^2 + 2x + 10                    - 2x^3 - 4x^2 + 2x + 10        -----------------------------------                                          0

Thank you for this information. This is the first time I have taken an online math course and was unsure how to type the equations. This is soooooo very helpful.

Which part of the explanation and examples in the article (in the link in the first post above) on the rules of web-safe math formatting did not make sense to you? Please be specific. Thank you!
