Thanks guys. I've just noticed another source of possible confusion. How's she to know that 5n is 5*n and not simply that n is a missing number - so it could be 51, 52 or whatever. Maybe she needs to know that 5n mean 5 times n. I'd overlooked that.
I'll show her the "Numeracy" section on the BBC site when she gets in tonight.
