You aren't *trying* to use each on a number.  A number looks like:

1
13.4
5

You are trying to use each on a Range, which looks like:

1..10
a..z

Unfortunately, ruby thinks you are trying to use each on the number 10. 
To fix the problem, you need to put parentheses around the range:

(1..10).each

Personally I always type:

1..10.e

and then remember I need the parentheses, which means using each() on a 
range requires too much typing.  So, I try to do this instead:

10.times do |i|
  ...
  ...
end
