At the moment my daughter is not particularly enjoying maths. She is in the "why do I need to learn this, there is absolutely no need for it in the future" phase. I can remember thinking something similar when we were studying exponents at school, but now I can see exactly how they work and that in fact they are very important in the real world. It wasn't a textbook that taught me all about exponents, but my daffodils. I think I probably started out with one small packet of daffodils about 10 years ago and have slowly divided them up around the garden and every year they grow exponentially until they now really brighten up the back garden at the start of spring.
I can remember thinking when I first bought the bulbs that they were slightly expensive, but hopefully would be worth the money. Now I am convinced that they were a bargain! It looks like they may need some more dividing next year.... I may need to start taking over a few more rice fields!
