"But what Phil Daro and others have criticized is our fixation on getting
answers at the expense of understanding math."
Phil, buddy, I hate to break it to you but if you don't get the correct
answer, you do not understand math. Can I repeat that? Calculating the
correct answer is the only proof that exists that you understand math.
Without correct answers, wheels will occasionally fly off of a car (who
needs correct torque settings anyway). Bridges will collapse (defining
tensile strength and ultimate loads is just so judgmental). Without correct
answers, a probe bound for Mars may just crash into the planet rather than
assuming an orbit above it. Petroleum refineries will occasionally blow up
because pressures were too high.
BTW, Phil; do you worry about it if the decimal on your paycheck is
misplaced an order of magnitude or two? Instead of a paycheck for $10,000,
you suddenly find you are in possession of a paycheck for $100. Is
understanding the process still more important than coming up with the
correct answer? | b********n

This is total insanity.Three plus four equals eleven . Ok even nazis did not
attempt shit like this.Because they did not want german's to be morons and
con artists .They are teaching kids to believe in fairytale shit.So when the
government tells them something that makes no sense they will believe it no
matter what. Even smart third graders will go insane over this. If i lived
on the border with mexico.I would send my kids to mexican schools. lol&#
