Examples
Find the calories per meal item, then multiply by the number of servings for a meal:
g.V().hasLabel('meal_item').as('a').
inE('includes').as('b').
math('a*b').
by('calories').
by('numServ')
Note that two by() statements are used to retrieve a particular property for each math variable used, calories for a and numServ for b.
