By grasping the inner workings of math structures, you can make sense of all kinds of numbers – without a calculator or a computer!The written addition most of us learn in school relies on simple and slow systems like “carry the 1” to get answers. There is an alternative – Vedic math moves at the speed of thought. Instead of summing columns and moving from right to left, Vedic math starts on the left. Add the largest numbers in your head, remember this figure, sum the smaller numbers – and then just total the figures in your head!By holding numbers in your head while calculating others, you strengthen your working/short-term memory. This mental sharpness pays off in all parts of your life – from remembering names to articulating your thoughts more clearly.

INTRODUCTION

Without mathematics, there’s nothing you can do. Everything around you is mathematics. Everything around you is numbers.

~Shakuntala Devi

Everything around us is made by numbers; the technology we are experiencing today is made possible by the use of mathematics. According to National Math and Science Initiative, out of 20 fastest growing careers, 15 out of them require a background in math and science. This fact is supported by an article from Investopedia published August 2016, the top 10 highest paying jobs require science and mathematics such as surgeon/physician, petroleum engineer, data scientist, corporate executive, air traffic controller, and pharmacist. This tells us how important mathematics in our everyday life, this also reminds us that mathematics is hard when we are studying in primary and secondary school. But is it really hard? Or do we just think it’s hard because it seems complicated?

In the latest ranking of the top countries in math, reading, and science, 7 out of 10 top countries in mathematics are from Asia. These are Singapore, Hong Kong, Macao, Taiwan, Japan, China, and Korea. Although Canada made it to top 10, Asian countries still dominate the 2015 PISA average scores. How does this happen? The reason is foundation and the series of exams required to take before leaving a certain level, for these reason students who enter college are one of very few who survive the series of evaluation.

As I said a foundation is the key to becoming efficient at math. Of course, not all of the countries would like to adapt their style because of its influence by their culture but there are certain parts of it that worth benchmarking. For example the very famous Singaporean mathematics, they use an actual curriculum they teach in kindergarten to sixth grade. In Singaporean math, they use an actual object and use it as a counting block or a drawing to represent a problem to easily solve it. The method is very efficient if you started learning it from the very start.

Japanese on the other hand had their version of counting using lines, they use it in multiplication. They draw lines on the paper to represents the digits, the lines are diagonal or perpendicular to each other. Then they count the number of points of intersection and write it down. It is a good way of multiplication although you will need a lot of papers to draw your line when the numbers get’s larger.

There is another good foundation known as mental mathematics, this method originated from India it is locally known as Vedic mathematics. Vedic mathematics has a complete set of techniques from addition, subtraction, multiplication, division and even squaring numbers or getting the square roots of a number. It is a really fast method that doesn’t need a pen or paper to be an expert, but for beginner, it is advised to use, at least for assurance that you follow the procedure correctly.
