It's that time of year, the one all the kids have been looking forward to – World Maths Day! A day to remember all those formulae that you studied so hard in school, remember those?
Luckily, to jog your memory, IBTimes UK has put together a little quiz to see just how much you've forgotten. The following are real questions from past or sample exam papers for KS1, KS2, GCSE and A-level, though some have been slightly formatted to fit a multiple choice quiz.
Find out whether your maths skill is less than that of a six-year-old or if you could skill pass your A-levels with flying colours below...
