# 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 ## Rust Installation Refer to the [exercism help page][help-page] for Rust installation and learning resources. ## Writing the Code Execute the tests with: ```bash $ cargo test ``` All but the first test have been ignored. After you get the first test to pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests to pass again. The test file is located in the `tests` directory. You can also remove the ignore flag from all the tests to get them to run all at once if you wish. Make sure to read the [Modules](https://doc.rust-lang.org/book/second-edition/ch07-00-modules.html) chapter if you haven't already, it will help you with organizing your files. ## Feedback, Issues, Pull Requests The [exercism/rust](https://github.com/exercism/rust) repository on GitHub is the home for all of the Rust exercises.
