Mathematics

We all require some numerical skills in our lives, whether it is to calculate our weekly shopping bill or to budget how to use our monthly income.

Mathematical intelligence generally represents your ability to reason and to calculate basic arithmetic computations. It also helps you to understand geometric shapes and manipulate equations.

If you have a firm knowledge of arithmetic, and a good understanding of analogies and equations, then when faced with a mathematical problem you will be able to analyze it and explore the many alternative solutions

Mathematical intelligence is a strong indicator of general intelligence because many every day mental tasks require arithmetical operations even though numbers may not be involved.

Example mathematics questions

Spain, Belgium and China comprise group 'A' of a soccer competition. In this group two countries will qualify for the knock out stage. How many different ways can these two teams be ordered?
