Amazing! I like the fact that you can copy your previous line into the next box down then just edit it. Is it possible to simplify the sample expression that is displayed, prior to displaying? I saw (-5y + (-40)) in an algebraic fraction question.

Very nifty! It might be clearer if you said something like: "Enter your working one line at a time and you'll be told whether it is correct.".

I deleted the trig identity formula sheet sentence. I've retained "Use appropriate identities and algebraic techniques" as I want to emphasise that both may be required.
