You see them all the time on social media - math problems or math riddles.  However a recent math problem is going viral and has received lots of guesses as to the correct answer.  This latest question about a man buying and selling a horse, should be easy for someone in Wyoming, right?

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

Thanks to everyone who took a shot at solving this math problem! Now lets show you the correct answer and why.

This is actually a math question that most people over think because it's actually two separate transactions for the same horse in this riddle.

The man bought a horse for \$60 and sold it for \$70. The man then bought the horse again and sold it again, which is a seperate transaction from the first. So the math looks like this:

(-\$60) + \$70 = \$10 profit.  Then he did it again (-\$80) + \$90 = \$10 profit and when you add up the results from the two transactions the man made \$10 in each transaction. So \$10 + \$10 = \$20, the man made \$20.

If you didn't get the correct answer, don't worry you're not alone, here's what everyone guessed.
