Dylan has started to multiply numbers. He already knew from experience that 'two and two are four'. Today he noticed that Mummy had placed two picture frames on each of three walls. Excitedly he tried to convey some new discovery, as follows:

DYLAN: Oh! Oh! Four and four.
DADDY: Four and four?
DYLAN: Two and two and two.
DADDY: How many is that?
DYLAN (without counting): Six.
