Suppose you want to know the length of the line BD:

  1. Select BD.
  2. The Calculate Output palette offers output as both numbers Real and expressions Symbolic. Click on Symbolic if its not already in front, then click the length output.

An expression appears, showing the requested length in terms of the two variables, a and b. Its selected, allowing you to move it wherever you wish.

 

The double arrow => that appears to the left of the expression indicates that the expression is an output that the application has calculated.
