Reference Manual for the MathML Editor

Math editor features

This module explains how to open the Math Editor, create math, edit existing math, and keyboard shortcuts. There is also a separate tutorial page with examples showcasing the features.

At the end of this module are nuances and limitations of the editor. Please, let us know which ones you'd really like to see incorporated!

Opening the editor

When editing a Module using using Mozilla's Firefox browser, click on a part of the module to open a blue editing box . On the top-right hand side of the box is a "MathML Editor" link which will open up the editor .

Launching the Math Editor
Begin editing and in the top-right corner is a MathML Editor link
An empty Math Editor
Once clicked, a popup window will appear containing the Math Editor

Using the popup window

The popup window can remain open while editing a module and can even stay open while editing several modules. At any point one can close the window, but the contents of the editor will be lost.

User interface

The Editor has 4 main sections, detailed below. The toolbar provides a way to insert new operations, a navigation tree to show where the cursor is located, and standard buttons for undo, preview, and source editing.

The main editing area is located below the toolbar and contains the math that is being edited.

Toolbar

The toolbar contains a row of buttons representing categories of different mathematical operations. These are enabled when something is selected in the editing area . Note: The editor does not infer multiplication and addition. See Nuances for how to insert next to existing math by wrapping existing math. Explain the different sections, when it's enabled, how things get inserted, and Keyboard Entry for things.

Menu

Clicking a category in the top row of the toolbar will open a menu of mathematical operations to insert. To the right of each operation is a name that can be entered from the keyboard at the cursor position in the main editing area . For example, instead of using the toolbar to enter the symbol for pi, the user could enter " pi " or " <pi/> " (the MathML version of pi) in the cursor and press the Enter key.

Path

Shows the path to the cursor location. Math is organized in a tree-like hierarchy (see Navigating Math ) and the path represents where in the tree the cursor currently is. The path (and context ) are important because they define what can be inserted and where it will go.

Undo/redo

These buttons allow the user to undo an operation such as deletion or insertion. See Keyboard Shortcuts for details on using these features from just the keyboard.

Preview

Shows what math will look like when module is published. To resume editing, one must click the Preview button a second time.

View source

Math in Connexions is represented in an XML format known as MathML. Clicking the View Source button will allow editing of the raw MathML.

Editing area

This is the main area for creating math. It begins empty, but math can be pasted directly in here from Connextions. The tutorials contain instructions on moving math from Connexions to the math editor and back. The editing area is the most important part of the editor and as several subsections, outlined below:

  • Math is structured like a tree .
  • Colors are used in this area to denote required information and contextual clues.
  • Content vs Presentation Math discusses the two different types of math the editor supports.
  • The cursor is discussed in detail below, including navigation and different editing modes.
  • Since the exact location of the cursor may at times be ambiguous, the context provides visual cues.
  • Keyboard strokes are discussed in detail.
  • Finally, empty blocks are discussed below.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

Economic growth as an increase in the production and consumption of goods and services within an economy.but Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
