Extension Maths

I'm doing a stupid extension Maths programe at the Uni on Mondays at the moment. Well, I went for the first time today.

I really don't like the whole concept of it. You hae to give up your own time, afterschool, to do extra maths! And then they give you homework and it just seems pointless! And anyway, hows it gonna help your future? I mean, your gonna cover it all in normal classes eventually, and so doing it early in extensions just gonna make it more boring when you actually do it in class. If that makes any sense at all.

We were just doing some random problems today. Like, kinda algebra and problem solving mixed together.

Here's one of them. If your interested read it. If your not just skip it.

The average weight in a group of boys was calculated. David, who weighs 39kg, joined the group and changed the average to 51kg. Ben, who weighs 61kg, then also joined the group, putting the group average up to 52kg. What was the average weight of the boys in the group before Ben and David came along?

Can you do it? I couldn't. But then the teacher explained and now i can. Which is a good thing, I guess. But I still hate doing extra maths.

BTW; I'm only doing it cause my parents bribed me into it. Mum actually bought me the last few of the books in Jhon Marsden's The Tomorrow Series, and then said that I couldn't read them unless I tryed this maths thing. I really had no choice. *sigh*
