Young Robert's dreams have taken a decided turn for the weird. Instead of falling down holes and such, he's visiting a bizarre magical land of number tricks with the number devil as his host. Starting at one and adding zero and all the rest of the numbers, Robert and the number devil use giant furry calculators, piles of coconuts, and endlessly scrolling paper to introduce basic concepts of numeracy, from interesting number sequences to exponents to matrices. Author Hans Magnus Enzensberger's dry humour and sense of wonder will keep you and your kids entranced while you learn (shhh!) mathematical principles. Who could resist the little red guy who calls prime numbers "prima donnas", irrational numbers "unreasonable", and roots "rutabagas"? Not that the number devil is without his devilish qualities. He loses his temper when Robert looks for the easy way out of a number puzzle or dismisses maths as boring and useless. "What do you expect?" he asks. "I'm the number devil, not Santa Claus."
