If you have a mathematical question to answer,
you can do it all yourself, or you can let AutoMathic help you do
it! With AutoMathic, you focus on specifying the problem, and let the computer do the mechanical work of solving it! 
The documentation has lots of examples throughout the main body, in the quickreferences, and in the lexicon... The examples were chosen to demonstrate not only AutoMathic's vocabulary, but also a wide range of its grammar and default knowledge. By seeing examples of its language in an understandable context, the user should begin to learn AutoMathic's "dialect" of English in the same way they might learn a foreign language by being immersed in it.
