# Wordy
Parse and evaluate simple math word problems returning the answer as an integer.
## Iteration 1 — Addition
Add two numbers together.
> What is 5 plus 13?
Evaluates to 18.
Handle large numbers and negative numbers.
## Iteration 2 — Subtraction, Multiplication and Division
Now, perform the other three operations.
> What is 7 minus 5?
2
> What is 6 multiplied by 4?
24
> What is 25 divided by 5?
5
## Iteration 3 — Multiple Operations
Handle a set of operations, in sequence.
Since these are verbal word problems, evaluate the expression from
left-to-right, _ignoring the typical order of operations._
> What is 5 plus 13 plus 6?
24
> What is 3 plus 2 multiplied by 3?
15 (i.e. not 9)
## Bonus — Exponentials
If you'd like, handle exponentials.
> What is 2 raised to the 5th power?
32
