Add math equations solver

[vieiraroger]

What would you like to be added: I would like to add a new feature that makes yoda solver math equations like this:

• 5 power 3 -> yoda should return "125"
• 3 * 3 = 7 -> yoda should return "False 9 != 7"

Why is this needed: Yoda is personal assistant, and will help people with simples or complex math equations, and will be a good way to me get my first commit on this repository.

What do you guys think about this possible new feature?

@vieiraroger this sounds like a great idea, I was just wondering how you are approaching this, I.e., are you looking to use Python packages such as numpy/ sympy for this.

@manparvesh @vieiraroger doesn't seem to be working on this anymore, can I pick it up?
