I’ve seen similar videos which I found interesting, but the traditional methods are actually shortcuts compared to these esoteric methods.
What is truly a waste of time are the “NEW” “ENLIGHTENED” methods such as the old NEW MATH and the crap Common Core shoves down teachers’ throats. The time spent screwing around with this nonsense would be better spent in practice, which builds automaticity. Once you just KNOW the results of fundamental computations, you can discard all the methods. Then higher math is a breeze.
Their objective is control...not enlightenment.
Control requires ignorance of the Truth.
I see a portrait of Obama staring up at the stars with a glint in his eye.
All a lie...but nicely packaged.
