The revised lead up is much improved. I like that it clearly states that building on existing knowledge is an instance of reuse. I didn't make that connection at first.

I messed a bit more with the math example. It's hard to make the second sentence correct and user-friendly. Maybe we should delete it: people who know algebra will know why its a pre-requisite without our saying why and for people who don't the further explanation seems confusing. Just a thought.

Hi Alison,

I think the lead-up works better now as well.

I'm OK with dropping the second sentence with the order of operations -- it was included for those who may not be familiar with the concept. Given that its an example -- it should be OK to delete this.

I made another attempt at the example to simplify the explanation. I think this one works OK. I agree it's nice to have a little bit of explanation/example for those unfamiliar with the concept.

That works nicely :-)

Now we are catering for all learners!
