Okay, I now feel the urge to come up with new equations to allow young children to do the most complex of college formulas. Let's begin with some... Let's tack the topic at hand, to see mathematical formula are not hard to understand, okay?
Scary, hey? Let's see if we can find a pattern for the two, and, then find a way to do maths regarding these two for the kids, so they can prepare for college, to see if they like this sort fo thing?
[A] This would be positive [c] minus [c] = [0]. Then, positive [s] minus [s] = [0]. Four symbols eliminated so far. Then, this centre equation of the first joules [J] * [d] = [B]. That is the answer of the first one, [energy] or [joules] times by [distance].
[B] For this second one, seeing as how we found the middle of the first so easy, would be to multiply the first answer by [f], of course.
As you can see, anyone in grade eight might be able to do this easier than they teach algebra, yes? It would also excite them more, to find these things so easy to do, as I find them to teach, of course.
