`1` ```exercism fetch haskell wordy ```

# Wordy

Parse and evaluate simple math word problems returning the answer as an integer.

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

## Hints

This is a perfect opportunity to learn some Attoparsec or Parsec!

## Getting Started

For installation and learning resources, refer to the exercism help page.

## Running the tests

To run the test suite, execute the following command:

 `1` ```stack test ```

#### If you get an error message like this...

 `1` ```No .cabal file found in directory ```

You are probably running an old stack version and need to upgrade it.

#### Otherwise, if you get an error message like this...

 ```1 2``` ```No compiler found, expected minor version match with... Try running "stack setup" to install the correct GHC... ```

Just do as it says and it will download and install the correct compiler version:

 `1` ```stack setup ```

## Running GHCi

If you want to play with your solution in GHCi, just run the command:

 `1` ```stack ghci ```
