**Division and multiplication is dividing** and multiplying numbers. This is the first of our 11-plus Maths quizzes on multiplication and division. You should be able to do most of this stuff in your head. Knowing your times tables is always useful when it comes to multiplying and dividing.

You may be great at addition and subtraction, but not so good at multiplication and division. It's definitely worth spending some time practising these valuable skills. Simple multiplication and division are used by us near-enough every day. You don't want to find yourself out of pocket because you couldn't do an easy division calculation.

Always remember in tests and exams to read the questions carefully to make sure you have understood what is required. Try these quizzes and see how good you are.
