Hi!
My name is Sergey and I make tools for developers who use Couchbase database.
When I calculate an expression like the following:
e = Calculus::Expression.new("-2 * -3")
e.calculate
I get an error:
NoMethodError: undefined method `*' for nil:NilClass
from /Users/ilya/.rvm/gems/ruby-2.0.0-p247@gaussian/gems/calculus-0.1.5/lib/calculus/expression.rb:131:in `block in calculate'
