There was a video in my inbox of the convoluted way that the Federally mandated school curriculum teaches subtraction.
This Math teacher actually attempts to defend it. The idea is you subtract by “counting up”from the small number to larger number, by counting in groups of 5 and 10
Not having been taught the technique, I’m pretty sure this is roughly how an abacus works – still widely used in Asia. Welcome your Manchurian overlords. Teaching how an abacus works without using an abacus is ummmmm confusing.
One of the opening preemptive salvos my Obama community organizing nephew launched in my direction when I arrived in NC was how ignorant the backward people here are who are opposing a uniform Federal Standard. He works for Microsoft and Bill & Melinda Gates are the force behind this movement. It may be time to bite the bullet and end my relationship with Microsoft when they pull support for Windows XP.
Next time I’m over for dinner, I’ll ask if he supported No Child Left Behind.
