Error in irb with Math.log

Hello fellow learners!

If I follow the instructions in the course and type in the following in irb:

>>Math.log(12, 3)

I receive the following error:

ArgumentError: wrong number of arguments (2 for 1)

But I do not understand why. Am I missing something?

Thank you in advance!

Cheers, Matthew

What version of ruby are you using. I'm not aware of any version that would cause this problem but it might help hunt down the problem.

Hi Patrick, thank you for offering to help me hunt down the problem! I just started up irb on my mac terminal and wanted to reproduce the error, but for some reason i did not receive any error message this time. Since answering the question I most likely updated my ruby installation via homebrew. Non the less quite weird, since I remember basically copy-pasting what i had input in the terminal into this forum, when i originally asked this question and being able to reproduce the error a month ago. Anyway, it seems to have taken care of itself. :-)

Cheers, naano
