Mental Mathematics and Rapid Calculations
Doing calculations quickly in your head
Tricks and Techniques to do calculations quickly in your head.
Why Mental Maths?
Mental maths is the practice of doing calculations in one’s head without the need of paper, pen or calculator. One can think of it as manipulating numbers in the mind. We do mental maths every day. Whether it is making calculations in connection with an occupation or working out the grocery bill most of us tend to use methods we learnt as children in school. But those methods are not the only ones available to us. The time and effort put to learning faster or easier to apply methods can be well worth while.
Of course, many will argue that we now all have a calculator to hand in every life situation, thanks to ever-evolving smartphones. However, that’s not to say that mental maths skills are now redundant. There are plenty of benefits, stemming from good mental maths skills development.
It can help:
- Stimulate the brain : Practising mental maths keeps our brain sharp and boosts learning capabilities. While mathematical skills are supposed to be a task of the left brain, mental maths stimulates the right brain which is responsible for imagination, visualisation and creativity. It requires one to think of creative solutions and visualise numbers; which involves using the right brain.
- Improve observation skills : It helps to build a relationship between different things; in this case, numbers. One becomes aware of how numbers interact with each other, which is an important skill required to love maths. Math concepts are built on each other and getting a sense of numbers is important to understand complex concepts.
- Memory: Mental maths relies heavily on memory.
- Self-confidence: Being able to get the correct answers quicker than most people builds your self-confidence.
- Succeed in Exams: Students preparing for certain exams, (such as the GAMSAT) particularly where the use of a calculator is not allowed, will need a certain competency in mental maths. Because it lets you work faster you are less likely to run out of time in exam, and will have more time to concentrate on more difficult parts.
- Keep up in class: You can follow the teacher in class sensibly. You are not missing what the teacher is saying because you are still trying to figure out the last statement.
- Have fun: You can do it to test your yourself, amaze your friends or just to pass the time like doing a crossword.
