You know the exact same argument happens every generation Itnetlolor. guess what, it's not happening. enjoy.
If a trend can be drawn, it's that uptight parents tend to produce hipster kids, and hipster parents tend to produce uptight kids. It cycles back and forth between generations of straightbacks and screwoffs.
By way of examples, most of my friends had hardcore parents who forced them through Boy Scouts, band camps, and absolutely no R-rated movies until teenagehood. They're all addicted to grotesque anime and homemade fireworks. Then there's me, a few years of burnout away from becoming the liberal Henry Kissinger. Why? Because I was raised by a rock'n'rollin', pot smokin' single father, and one of us had to be the adult.
My sympathies for your future children Aqizzar.
Also, doing arithmetic from left to right isn't hard. I figured out how to do it years ago without ever being instructed to do it that way. It's, surprisingly, faster than the normal way.
Take this problem:

For here, we add 2 and 4 together to get 6, then move right to add 6 and 3 to get 9. Then we move right again and add 5 and 8, but since that's 13, we backspace and add 1 to 9, which is ten, so we backspace again to add that to 6 to get 7. So we have 70,3 right now, and we move right again, add 4 and 9 to get 13 again, we backspace and add 1 to 3 for 4. Then we move right again, and the last digits are zeros, so no change.
Thus the answer is 70,430.
Granted, this is easier when done in a digital medium where you can backspace. You can even do it with subtraction. I don't think you can do multiplication/division this way though...
