And s/he was right. Most students who were brought up with calculators in math class cannot do basic math without one today. When shopping in groceries, they have no idea if one product costs more than another by weight. They're easy to bamboozle with the simplest misrepresentations of numbers. Is one choice of product really better than another, fractionally, or corrected for a shifted baseline? They don't know and can't use basic algebra to find out.
This is bad -- an F grade for the education system that let them slide by without learning an essential skill. The chinese aren't this lazy. And if we persist in not learning this, America's future will regress to us asking them, "Do you want fries with that?"
