[post_page_title]Teachers shouldn’t trust them[/post_page_title]
Okay, this one is hard to spot unless you really have a knack for high school level math. This is a printer being sold at an office supply store. You might think that the error here is in the pricing, but you’re wrong.
If you look in the background, you can see that they have the quadratic equation on the advertisement that claims these printers are trusted by teachers. But their version of the quadratic formula that they have on there isn’t even correct! It’s 4ac, not 4ab, guys. Teachers really shouldn’t be trusting this company….
