Who doesn't love algebra at the weekend ? A spot of calculus on a Sunday? No? Don't worry, you're not going to need a calculator for this.

If you'd like to WIN  a Momiji doll then all you have to do to enter is tell us the mathematics for your perfect weekend.  

First, pick a Momiji doll then + a place + a person + a food...they should all add up to make your ideal weekend!

So I think this weekend, mine would be: 

ADVENTURE + Norway (I really want to go there!) + my mum (she wants to visit Bergen so we can research our family tree) + Vafler (Norwegian waffles!) = my perfect weekend
