takes and adders generalisations


an intention for this task is to
  • work on patterns in various sums
  • reach a conjecture about how the patterns can be generalised 
  • prove this using (a) diagrams (b) algebra
thanks to the teachers in Derbyshire for their insights





















which questions are these?
what do the diagrams show?
