V3: [Go] Implement new Concept Exercise: numbers

[tehsphinx]

This issue describes how to implement the numbers concept exercise for the Go track.

Goal

The goal of this exercise is to teach the student how to deal with numbers in Go.

Things to teach

• This should introduce the int and float64 types (be basic number types in Go).
• It should introduce operations with numbers like multiplication, division, etc.
• This should also introduce the concept of zero values.
• should introduce the increment ++ and operators like +=, -=, etc.

My suggestion is to copy C# numbers exercise: https://github.com/exercism/v3/tree/master/languages/csharp/exercises/concept/numbers

Concepts

• numbers

Help

If you have any questions while implementing the exercise, please post the questions as comments in this issue.

I'd like to tackle this exercise if it's ok?

[tehsphinx]

Sure :) I assigned you, but feel free to do that yourself.

You can then also move it on the project dashboard to in-progress column and remove help-wanted status and add in-progress status. I'll do that on this one for you

[tehsphinx]

Now it's all yours 😄

Nice one thank you. :smiley:

I couldn't seem to assign myself to the ticket, think it's most likely that I haven't got a contribution yet into the project. I'll put up a PR adding myself to the maintainers list, which should sort that out!

[tehsphinx]

You also need to add yourself in the Go repo to the maintainers.json: https://github.com/exercism/go/blob/master/config/maintainers.json. That will somehow provide privileges for this repo. Don't know the details though. I think there will be an invitation email.

I've put an initial PR up for this exercise: https://github.com/exercism/v3/pull/480 but I currently can't modify the labels on the PR to addtrack/go to it, which is most likely related to needing the maintainers.json PR needing reviewed and merged (have opened that as well: https://github.com/exercism/go/pull/1330)

[tehsphinx]

Nice!

exercism/go#1330 is merged now :)
