Getting the Ruby method lingo down

I want to make sure I understand all these terms, so I took a stab at describing each line in this video's example code. Can someone check my "translation"? :) .

1. def add(a)

Defines method "add" which takes argument "a"

2. puts a + 2

Somewhat struggling with this one, oddly enough. Definition of method add: writes a + 2. 

3. end

Key word ending the definition of method "add".

4. add(2)

Calls method "add", passing "2" for argument "a".

Thank you!

Hey there,

Yep, you seem to have everything down for basic method syntax.

To help with #2, puts (which stands for "put String") is essentially the same as print. Both will output to the screen, it's just that puts will add a new line after execution and print will not. So, try not thinking it as "puts" but rather "put string" on the screen... it may make it seem to make more sense.

Great Job! :)

Thanks! In hindsight, "put String" should've been obvious, ah well!
