# 2.1 The basics

 Page 1 / 5
This module provides a basic user's guide to Connexions' MathML editor. In it you will learn how to access the editor, how to create, edit, and delete MathML expressions using the editor, and how to insert the MathML code into a module.

## Overview

This module covers some basic points of Connexions' MathML editor, now in beta testing. It is organized as a tutorial and will lead you through basic usage of the editor, though you can skip around the sections if you wish. The tutorial covers:

• how to access and use the editor
• how to create MathML expressions
• how to navigate through the structure of an expression
• how to edit expressions
• how to insert expressions created in the editor into a module
• how to delete expressions
• how to use the menu buttons to create and edit expressions

You will learn how to create the expression $ax^{2}+bx+c$ using keyboard input and also using the toolbar menus .

You will also learn about the basic layout of the MathML editor, the context of your cursor within the editing area, and how to select or highlight part or all of the MathML within the editor with key strokes or the mouse.

All of these aspects of the editor and more are covered in more detail in the MathML Editor: Manual .

## Accessing the editor

Currently, the MathML editor is only supported in Mozilla Firefox . If you use Internet Explorer or another browser, you can download Firefox for free under the link.

When editing a module using Mozilla's Firefox browser, click on an element within 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 .

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.

The editor has two main sections: the toolbar and the main editing area .

The toolbar consists of

• a Menu containing mathematical operators
• buttons for Undo/Redo
• a Preview button, which will display the math as it will look in a published module
• and a View Source button, which displays the raw MathML code

The editing area is the main area for creating math. It begins empty, but math can be pasted directly in here from Connexions, or created on the spot by either typing in expressions or using the toolbars. See the section Inserting expressions into a module below for how to move math from Connexions to the math editor and back.

## Creating expressions

When you first open the MathML editor, the Editing area should have one blank box in it, called a " block ". A block is an empty slot that can be filled with a number, variable, or longer expression consisting of at least one operator and its associated arguments.

Click inside of it to place your cursor inside the empty block.

There are two ways to insert math using the keyboard. The simplest way is to use keyboard shorthand notations for operators. These exist for simple algebra notations, and are similar to the buttons on a calculator (for instance, * for multiplication, - for negative or minus). A full list of Keyboard shortcuts is located here .

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong

Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well

for teaching engĺish at school how nano technology help us
Anassong
How can I make nanorobot?
Lily
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
how can I make nanorobot?
Lily
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
