What makes WIRIS editor a powerful tool is its ability to relate different expressions and symbols within a formula.

Let us start by seeing how to write  ; there are two ways to do this:

• Write first the square root symbol, and then the x inside it.

  Click on the icon in the General tab

• Type first x and then put the square root symbol around it:

  Type x

Let us see now how to use a symbol that involves two expressions, and let us write:

As before, we have two ways to do this:

• Draw first the fraction and then fill in numerator and denominator.
