###### MathML (from the WIRIS manual)

As you are typing math expressions into your participation posts in the New Classroom,
do not type them inline (inline means you are typing the expression all on one line using symbols such as **^** for exponents and **/** for fractions).
Instead of typing your math expressions inline, use the WIRIS Math Expression Editor (as shown by the red arrow in the graphic below).

If you have trouble
starting the Math Expression Editor and you are using Windows 8, read this Word document for a possible solution:

Windows 8 IE Metro and WIRIS Editor

While you could type your math problems inline such as y=(2/3)x^3-(1/2)x^2+5x-(3/4), this
format can be very difficult to read and often stifles the discussion. Using the Math Expression Editor is not
required, but it is **strongly** encouraged. Many templates are provided to type fractions, exponents, radicals, matrices, and subscripts.

To open the Math Expression Editor, click the yellow, principal square root symbol on the message toolbar as shown by the red arrow in the graphic above. You will see the Editor in a pop-up window with nine tabs (as shown in the graphic below). You will also notice that the company that created this Math Expression Editor calls it the WIRIS Editor:

The default tab is the General Tab where most of the templates you will need are located. See the section below on the General Tab for more information.

After typing your math expression(s), press the ACCEPT button to insert your expression(s) into the body of the message post you are typing.

Notice that the general tab above is divided by separators into 9 logical groups as shown in the graphic below:

Fraction templates; Principal Square Root template; Root or Radical template for those with index other than 2

Superscript template; Subscript template

Dynamic Parentheses and other grouping symbols templates. The templates are dynamic -- they autosize depending on their contents

Binary operation symbols

Comparison (Inequality) symbols; Set Notation symbols

Empty Set symbol; Infinity symbol; Pi symbol

Copy, Cut, Paste, Undo, and Redo

Font formatting buttons -- Bold, Italics, AutoItalics (default), Font color, and Normal text for annotations

Font family and Font size -- note that these drop-down menus look dimmed out, but they are still available (bug??)

As you are typing math expressions, **do not press the space bar to format the characters**. The templates have been
programmed to space math expressions according to accepted standards found on the W3Schools website.

If you choose to type annotations to explain each step in your
math expression window, put those annotations on a separate line and format them in Normal text as shown in the graphic below. The button for Normal text is in Group #8 and has a T| on it.

You can insert the template first then put the contents into the template's placeholder(s) -or- you can type the contents first, highlight/select the contents,
and then click the appropriate template on the toolbar.

To exit out of fractions, subscripts, superscripts, radical expressions, or any other template where you are not typing
on the normal baseline for the rest of the expression, press the right-arrow key on your computer keyboard or click with your mouse outside the template to return to the
normal baseline of the expression.

The grouping symbols in Group 3 of the General Tab are "Dynamic", which means they will autosize to adjust to the size of the contents. Be sure
to use these grouping symbols if the expression contains fractions, subscripts, superscripts, radical expressions, etc. where the font size or the font baseline is not the default. See the example below:

Use any of the first 4 icons/templates in the first group of the Matrices Tab. Once you click on the template, you will be able to
choose the size/dimensions of your matrix table. You will also see a new Contextual tab to allow you to easily insert columns or rows.

DIVIDING LINE: If you want to create an augmented matrix
**with the dividing line**...

Create the square coefficient matrix template (without the augment column):

Put your cursor inside the square braces but to the right of the coefficient matrix (where you want to insert the augment column). Insert a one-column matrix without square brackets around it. You can't just create a 3 × 4 matrix to begin with because you need that augment column to be separate from the coefficient matrix:

Highlight that augmented column and go to the decorations tab and choose "Enclose left" as shown by the red arrow below:

Then you get what you want. It takes time but it looks good. For the purposes of this class, you can type matrices in your posts without that augment line.

The Decorations Tab allows you to place vertical lines before a template (useful in creating the dividing line in an augmented matrix).
There are also templates to cross through various characters to show cancelling. Finally, you will find templates to draw a box or a circle around a template -- useful to draw a box around the answer
to a problem.

Symbols Tab

Arrows Tab

Greek & Letters Tab

Scripts & Layout Tab (with Kerning at the far right)

Big Operators Tab

Calculus Tab

On about half of the tabs, there are too many templates or symbols to fit in a particular group.

For these groups, you will see a flyout menu indicated by a light, gray arrow.

The good thing about the WIRIS Math Expression Editor is that it does most of the formatting for you. You don't have to know
too much about formatting your math expression for it to look good.

1*b* is the default font formatting, called Auto*Italic*.
There are five math functions that are reserved words (sin, cos, tan, log, ln). All text
is in italics by default unless the Editor sees one of those reserved words. Then the reserved words are typed in non-italics. If you type a word such as "rectangle" that contains
a reserved word, you can fix it by putting the cursor inside the reserved word, deleting a letter, then retyping the deleted letter. Alternately, you can highlight/select the entire word and
use the italics key to turn the entire word into italics.

To type text annotations, which explain your computations, press the Enter key to be on a new line,
and then switch to Normal text. The button for Normal text is on the General Tab -- the capital letter-T with a box around it: T|.
You will see a blue text box around normal text as you are typing it, but that blue box appears in the editing window only -- it will not appear in accepted expression.
See the example below.

The Font family and Font size menus on the General Tab (see graphic below) are available even though they look dimmed out. (BUG?)

A button on the General Tab allows you to change the color of text (see red arrow in the graphic below). You can use colored text to identify parts
of a math expression you are changing. Any decorations you place on or around the characters with colored text will also be colored.

The WIRIS Math Expression Editor has been programmed to format and space math expressions according to standardized rules.
**You will never have to insert spaces between characters.** If you do want to adjust the spacing between characters (called "Kerning"), use the templates at the end of the "Scripts & Layout Tab" as
shown in the graphic below.

The template to align equations is available on the "Matrices Tab". This is one template that must be selected first before typing the contents.
You cannot type the contents first, highlight/select the contents, and then click the align template.

The WIRIS Editor manual tells us that "mathematical operations can be nested, and so symbols can contain expressions with symbols.
Many symbols expand to match the size of their contents; note, for instance, the variable size of the square root symbol:

Parentheses also will scale as expected if you do them with the
icons on the General tab. If you want simple
non-scaling-parentheses, just type them with the keyboard."

Shortcut keys you can use instead of the templates on the toolbar are: Ctrl+up arrow for superscript; Ctrl+down arrow for subscript; Ctrl+B for bold; and Ctrl+I for Italics.

Other shortcut keys you can use instead of the icon buttons on toolbar are Ctrl+X for cut, Ctrl+C for copy, and Ctrl+V for paste.
You can even copy some characters from outside the editor. If you are pasting text into WIRIS Editor, set the text mode to Normal first.

**SMART DELETING (from the WIRIS Editor manual):**

*WIRIS editor* works internally with MathML. Fore more info, there is a *WIRIS editor* MathML coverage page.

If you copy formulas from the
WIRIS Math Expression Editor into the *Notepad*,
you will get a chunk of MathML code:

*Microsoft Word* (2007 and newer) understands MathML and converts it into a formula. As far as we know, *OpenOffice* and *LibreOffice* suites can import MathML, but only from files, and only formulas one by one, that is very impractical. Other applications if they do not understand MathML will see it just as a chunk of weird text.

You can paste a valid MathML formula into the
WIRIS Math Expression Editor. You can even paste slightly invalid MathML, and it will be rendered as well.

In some special cases, you may need to see or edit the internal MathML of a formula. You can do it with the key combo `Ctrl+Shift+X`

.

You can copy formulas from Microsoft Word (2007 and newer) into the
WIRIS Math Expression Editor, if you configure Word's Equation Editor to Copy MathML as shown in
the graphic below.
