The Simple Math Riddle That’s Stumping The Internet

God blesses us with incredible minds that are great at problem-solving! Some of us are very creative problem solvers, while others are analytical when it comes to finding a solution. Now, there’s another viral math question that’s stumping the internet… are you smart enough to solve it?

The riddle was posted on Mumsnet by a user named PeerieBresks. Mumsnet is a parenting website and forum, and this seemingly-simple riddle racked up nearly 500 comments as other users began debating the answer. The text of the math question reads as follows: A man buys a horse for $80. 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?

Users have posted their answers to the math riddle on the Mumsnet thread and they ranged from $10, $20, $30, to breaking even. So, what’s the real solution? What seems to be throwing people off most about the question is the fact that the man sells the horse for $70 and then buys it back for $80, which makes it look like he spent 10 more dollars. But, the correct way to solve the problem is to think of the two transactions as separate: -60 + 70 = 10 and -80 + 90 = 10. So, the man in the riddle makes $10 with each sale, therefore he earns a total of $20. Did you get it right?
