Hello,

I’m writing a tutorial for beginners, primarily aimed at Teachers and  
Students.

I’ve written the following tutorial.

[http://www.oriontransfer.co.nz/education/learn-ruby/lesson-0/index](http://www.oriontransfer.co.nz/education/learn-ruby/lesson-0/index)

Any feedback would be really really helpful. Thanks to anyone who takes  
a look.

Any suggestions or feedback would be fantastic - what should I add or  
remove, what was not clear / etc.

Kind regards,  
Samuel

Hello,

I think there is a small error in the last example. It’s written:  
# Do you wear a watch? Ruby can help you out!  
puts “The time is: #{Time.now.to\_s}”

I think it should say:

```
         puts "The time is: #{Time.now.to_s}"

```

Oh yes, Thanks - I’ve fixed it 🙂

I haven’t read the tutorial, but this can be written as:

puts “The time is: #{Time.now}”

since string interpolation calls to\_s for you.
