Variables

It is possible to define variables. Variable to be defined may be written in any position in the equation, like:

• a = 458
• 458 = a
• a * 5 = 25
• sin(a) = 0.5

There can be at most one undefined variable used in the equation. If there is no undefined variable, the leftmost variable is considered to be undefined. The undefined variable may have only one occurence.
