# Numerical Computation Questions

Numerical computation questions involve the basic principles of arithmetic like addition, subtraction, multiplication and division. They also use mathematical terms and methods such as percentages, ratios, fractions and decimals. To score well on numerical computation questions you will need to make quick and accurate calculations. This type of test can be categorized as a speed test and is used to determine your basic numeracy. Obviously you will not be allowed to use a calculator.

If you are very rusty with arithmetic, try re-learning the times tables up to 12 and practice multiplication, division and percentage calculations. Practice can improve your test scores for all types of aptitude tests, so try as many examples as you can.

These questions are directly applicable to many administrative and clerical jobs but can also appear as a component of graduate and managerial tests. The speed at which you can answer these questions is the critical measure, as most people could achieve a very high score given unlimited time in which to answer. You can therefore expect 25-35 questions in 20-30 minutes.

These papers contain 30 questions and have a suggested time limit of 10 minutes each. The questions are presented in Letter/A4 format for easy printing and self-marking.

Numerical ability tests can be divided into tests of simple numeracy, where you are told which arithmetic operations to apply, and numerical reasoning tests where you are presented with some data and questions but the methods required to answer the questions are not specified. In all cases you need to prepare by practicing your mental arithmetic until you are both quick and confident. Your score in the simple speed tests will be very much influenced by your ability to add, subtract, multiply and divide quickly and accurately.

Preparation plays a large part in determining your level of success, and these sample questions should help you to face a test with increased confidence.
