It's another musical, mathematical Monday.
Last week, Patrick O'Brien scooped the prize with the answers "Electric", "Haircut" and "Seconds to Mars". Who will it be this week? Please send your answers (to all three equations) with the title "Pop Maths Week 4" to music.editor@guardianunlimited.co.uk and we'll pull one out of the inbox. Entry closes at midnight on Thursday 18 December.
If you're not sure how to play Pop Maths, check out THE RULES. Remember, the answers are all words from band names and not numbers! Some questions have multiple answers - any correct one is good for us.
Right, Pop Maths is off on its school holidays but we'll be back bigger, better and quite possibly with proper prizes in the new year - see you then!
