ST. LOUIS - All day long we've had a big response to a story we brought you on Today in St. Louis.

A dad has become an internet sensation, after posting his struggle while trying to help his son with math homework.

The assignment asks you to help a boy named "Jack" subtract 316 from 427. But instead of doing it the old fashioned way, which quickly gives you 111, this assignment instructs students to use a number line and problem solving strategies, which is the new "common core" approach used in schools.

So, the father of the boy trying to figure this out wrote, "Dear Jack: Don't feel bad. I have a Bachelor of Science degree in electronics. Even I cannot explain the common core mathematics approach. The process used is ridiculous and would result in termination if used. Sincerely, Frustrated Parent."

We asked our Facebook fans if they think the common core curriculum is helping students, and we received hundreds of comments.

"I can't help my third and fifth graders with their homework because they have to follow ten extra steps to come up with an answer that I was taught how to do in two steps," said Shannan Gilbert.

On the other side, Tina Rozar Lauer said, "I am a teacher, and think it is very good for students."
