WTF of The Day: People Are Really Angry Because This Math Strategy Says '5+5+5=15' is Wrong

What if someone told you that 5+5+5 doesn't equal 15?

Any sane person with a second grand education would call your bluff. But they'd be wrong. At least, according to the Common Core curriculum.

A photo of a student getting this answer wrong blew up on Reddit last week, causing mayhem across the Internet.

The "correct" answer to solving 5 times 3 would be 3+3+3+3+3.

Supporters of Common Core say that adding 5 groups of 3 together is correct because that strategy will help students once they reach more advanced math.

Back in September, a dad wrote a check in "Common Core math" to show how strange some of the strategies are.

And Common Core has become a hot button issue in the GOP presidential election. The Donald has come out against the academic standards while Jeb! has long support them.

"@RebelCapsGal: @realDonaldTrump THANK YOU for speaking out against Common Core and how horrible it is for kids!"
