Calling Ruby method from the command line

I have a program in a file called project1.rb. Inside this file I have a method called check_num(n). I simply want to call that method from the command line or IRB, but I can't figure out how and can't seem to find docs explaining how.

Here is what I've tried: 

$ ruby project1.rb check_num(100)

#=> -bash: syntax error near unexpected token `('

Can Anyone help me out with this?

ruby -r ./project1.rb -e "check_num(100)"

-r filename is same as Ruby require "filename"; and -e code evaluates Ruby code.
