This puzzle is from a document attached to a fence within the playground of a primary school, as shown to the right.
A = A+B=6
B = B+C=8
C = A÷B=2
Work out the value of A B and C.
A=4, B=2, C=6.
The metapuzzle is not hard for experienced puzzlists. I fear it must be too hard for primary school children.
