This trick combines a quick mental calculation with an astonishing prediction.

The Fibonacci sequence is a series of whole numbers in which each number is the sum of the two preceding numbers. Beginning with 0 and 1, the sequence would be 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233… etc.

Speed Addition Left to Right Approach

Most of us are taught to do math on paper from right to left. And that's fine for doing math on paper. But if we want to do math in our head (even faster than we can on paper) there are many good reasons why it is better to work from left to right.After all, we read numbers from left to right, we pronounce numbers from left to right, and so it’s just more natural to think about (and calculate) numbers from left to right. When we compute the answer from right to left (as we probably do on paper), we generate the answer backward. That’s what makes it so hard to do math in our head.

Missing Digit Math Trick

The Missing Digit Trick!

Ask a friend to secretly write down ANY number (at least four digits long). e.g. 78341.

Ask the friend to add up the digits... e.g. 7+8+3+4+1=23.

... and then subtract the answer from the first number. e.g. 78341 - 23 = 78318

Your friend then crosses out ONE digit from the answer. (It can be any digit except a zero) e.g. 7x318

Basics of Vedic Mathematics

After introduction to Vedic Mathematics, let us start with basics. It would be good to take multiplication, and for that any 2 digit number with any other 2 digit number.

Basic Definitions:

Vedic mathematics is based on the concept of placing the numbers either at the unit place or tenths or hundredth and so on. So for ease of understanding, let us use this legend:

Multiplication of Two Numbers using Vedic Maths

Today we will learn how to multiply two numbers having first digits same and sum of second digits is 10 using Vedic Mathematics methods.

Let's understand it through examples.

Example 1:  47*43

Here first digits are same, i.e. 4. Sum of second digits is 7 + 3 = 10.

This is exactly the conditions we are talking.

Multiplication Techniques Using Vedic Maths Part 1

There is no change when any number is multiplied by 1.When we multiply one number by another then it is increased and becomes further away from one. When 4 is multiplies by 5 it becomes 20 which is further away from 4 and 5. Using our multiplication techniques, we relate each number very close to another number called base. The difference between the number and the base is termed as deviation. Deviation may be positive or negative. Positive deviation is written without the positive sign and the negative deviation, is written using a bar or negative sign on the number

About Vedic Mathematics

What is Vedic Mathematics?

It is an ancient technique, which simplifies multiplication, divisibility, complex numbers, squaring, cubing, square and cube roots. Even recurring decimals and auxiliary fractions can be handled by Vedic mathematics. Vedic Mathematics forms part of Jyotish Shastra or Astronomy which is one of the six parts of Vedangas. The Jyotish Shastra or Astronomy is made up of three parts called Skandas. A Skanda means the big branch of a tree shooting out of the trunk.
