exercism fetch go 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?


What is 6 multiplied by 4?


What is 25 divided by 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?


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?


Running the tests

To run the tests run the command go test from within the exercise directory.

If the test suite contains benchmarks, you can run these with the -bench flag:

go test -bench .

Keep in mind that each reviewer will run benchmarks on a different machine, with different specs, so the results from these benchmark tests may vary.
