There’s nothing like a simple math problem to make you feel really stupid.

PeerieBresks posted a simple math riddle on Mumsnet, a parenting forum, and it racked up over 500 comments because people couldn’t agree on the correct answer.

Here’s the question:

A man buys a horse for $60. He sells the horse for $70. He then buys the horse back for $80. And he sells the horse again for $90. In the end, how much money did the man make or lose? Or did he break even?

Most of the Mumsnet users posted a sum between $10 and $30 and a few even said he broke even.

What do you think?

Scroll down for the answer.

The correct answer is: $20

The best way to tackle the problem is to approach each transaction as separate: -60 + 70 = 10 and -80 + 90 = 10.

The man made $10 with each transaction which adds up to $20.

A young boy tried to grab the Pope's skull cap

A boy of about 10-years-old with a mental disability stole the show at Pope Francis' weekly general audience on Wednesday at the Vatican auditorium. In front of an audience of thousands the boy walked past security and onto the stage while priests delivered prayers and introductory speeches.

The boy, later identified as Paolo, Jr., greeted the pope by shaking his hand and when it was clear that he had no intention of leaving, the pontiff asked Monsignor Leonardo Sapienza, the head of protocol, to let the boy borrow his chair.

The boy's activity on the stage was clearly a breach of Vatican protocol but Pope Francis didn't seem to be bothered one bit. He looked at the child with a sense of joy and wasn't even disturbed when he repeatedly motioned that he wanted to remove his skull cap.
