Ok, so this is more of a rant, but I've about had it with these expensive textbooks that (one) have errors and (two) make you do all sorts of convoluted things to get to an answer.
I suspect that the textbook questions are computer generated or something. Or else why would you be asked to solve simultaneous equations by graphing and get answers like 1.72 and 2.46. Seriously who can graph something and get those answers?
Anyone on here care to defend these textbooks? No wonder people get math phobia when solving a simple equation results in you needing to divide 5/12 by 4/7. Really? Why isn't math more problem solving? Where you figure out what the equations should be and you get a solution that is meaningful? Instead, my kids in algebra get these stupid lists of equations to solve that have no application, no purpose, and no history behind them.
OK, I'm done. Feels better. A little.
