# 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
## Running tests
Execute the tests with:
```bash
$ elixir bob_test.exs
```
(Replace `bob_test.exs` with the name of the test file.)
### Pending tests
In the test suites, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
commenting out the relevant `@tag :pending` with a `#` symbol.
For example:
```elixir
# @tag :pending
test "shouting" do
assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
end
```
Or, you can enable all the tests by commenting out the
`ExUnit.configure` line in the test suite.
```elixir
# ExUnit.configure exclude: :pending, trace: true
```
