It is 152, not 118 :-)
BTW you have not spelt #math-challenge correctly in your tag - you may wish to change it. At some point I hope we get tag suggestions popping up in the tag box to avoid typos making posts go astray.
Also, just poted my new Brainsteem #2
Good to see some momentum building with maths :-)
Thanks for your kind remarks @rycharde. Yes, answer is 152. Thanks for the call on typo in the tag. But it's too late now, we can't edit any post after 7 days.
