Can you give an example of a text book having students do something like that.

Edit I have two nephews that I help with doing math homework and I have never seen anything like what you are claiming.

It's very possible that your two nephews are not being taught common core math, but I have no idea to be honest.

That's not a textbook that is a picture that could easily be either doctored or a typo.

The picture isn't even saying what you claimed, nor is it wrong...
