Dr. Raj Shree Dhar, Nodal Officer, J & K Institute of Mathematical Sciences writes, "Mental mathematics refers to mathematical calculations that you do in
your head. It has been known to run almost every aspect of human life,
considering that from the moment you wake up you are always calculating
the amount of time it is going to take you to accomplish certain tasks."
Worth noting is that this type of mathematics does not necessarily reflect how good one is in mathematics in general. It is a skill and the only difference is that while some people can be fast, others might take ages to work on simple calculations.
There is need to develop mental mathematics in children from a very tender age. Funny enough, there are some techniques that, when followed, help in simplifying even the most complex of calculations.
For instance, it is possible for a child to calculate 1478+3456+98-29 in less than five seconds, without the use of a calculator or any other gadget. This has been made possible by the fact that mathematical systems are used in making mental calculations easy. East Asia is credited for developing most of these methods. Since most mental calculations often happen subconsciously, it is important to develop the art of constantly engaging in mental mathematics since it has proven health benefits to both the young and the old.
Mental mathematics is very interesting although many people tend to find it a bit difficult to master.
There are set methods that can help you achieve this faster than you can imagine. Vedic mathematics is one of them and is rated among the best methods available. It is one of the most recommended methods for the students who are preparing for any mathematical examinations or contests for that matter. Compared to other conventional methods of learning mathematics, Vedic mathematics tends to be more systematic, unified and simplified at the same time. It is a powerful tool for mental maths that encourages the students to develop their skills in Mathematics and at the same time gives them an opportunity to engage in some fun, giving them satisfaction and flexibility in the learning methods.
Most of us, when faced with maths problems, immediately reach for a calculator or a pen. One key to improving and expanding your math potential—whether you're a corporate executive or a high-school student—lies in the powerful ability to perform mental math calculations. Solving basic math problems in your head is a gateway to success in understanding and mastering higher mathematical fields such as algebra, statistics, and calculus. It's a skill that offers other lifelong benefits. Vedic way of learning mental math has quite a number of advantages. For starters, this method allows you to increase your speed up to 15 times faster than if you were using the conventional math.
