Just because you got through today without using algebra doesn't mean that you shouldn't have used it!
So often I hear people say they hate algebra! They go out of their way to explain how they don't use it in the real world and still get by, or make a ton of money, or [insert excuse here].
There are two things that I usually respond if I don't think it will cause further argument.
1. You actually are using algebra, you just don't realize it.
2. If you did use algebra, you might have made a better decision, saved money, saved time, or [insert excuse from above here] better.
Check out this article in the NY TIMES. I am both happy and sad to see sunlight being allowed this particular topic. I would love to see positive changes, but also know that most of the people who impact the way our education system works are not informed enough to make good decisions.
