What is algebra

Answers
Well goodness, where to start?It's a difficult question and there's going to be some gaps in this answer, but hopefully they won't matter too much. Anyway algebra is basically a way to do arithmetic (adding, multiplying and so on) without numbers. Most of the time, when we're trying to describe the real world, we don't actually know the value of something. Without algebra this lack of information would be a serious handicap. But you can start by pretending you know what it is, and then treating this "thing you don't know" as a proper number, means you can work with it like any ordinary number. This is hugely powerful because you can make some progress in solving the problem without the numbers, and hit on general methods of solving all problems at once. Without an example it's hard to show this. But as you come to learn algebra, and how it works, and start to extend it in all sorts of wonderful ways, you might begin to appreciate why it's so wonderful and so useful. Or you might hate it. But that's up to you.
