Course Setup   Adding Math Equations

Moodle supports TeX and Algebra notation to add mathematical expressions anywhere in a 

module where the HTML editor is used. Please note that  your  Moodle  administrator  must          

enable the TeX and Algebra  Filters  for these functions to work. 

Algebra 

There are a couple of ways to add mathematical expressions. For very simple expressions, you 

can use the superscript and the subscript functions in  the  HTML  editor.  More  complicated          

expressions (fractions, calculus, etc.) need more advanced formatting, using the algebra filter. 

This filter uses coding to create mathematical expressions.  

The good news is that it is very simple to use. The code looks like a mathematical expression 

you would type (like x^2 = y), except you enclose it in double  @  signs, like this: @@x^2 = 

y@@. The filter is flexible and can ignore spacing:  

     @@xy=z@@ is the same as @@ x y = z @@.  

     The filter can make full use of parenthesis for organization, so @@(length)/(height)@@ is 

a valid expression. 

Fig. 44 shows some examples of what the 

input  into  Moodle  would  look  like,  with  the                    

corresponding output.  

More complicated expressions   TeX 

Moodle  supports  TeX  notation  for  more        

complicated mathematical expressions. TeX 

expressions are always enclosed in double $. 

A TeX expression looks like $$sinx^2$$. TeX 

expressions can be more complicated.
