**Introduction**

**Do you want to get 10 times faster at calculations?**

**Do you want to master addition and subtraction?**

Mathematics has always seemed to be challenging to study for many. To make it friendly to learners, continued efforts, research, and advancements are continuously made throughout human beings’ history. In ancient times, easy methods of mathematical operations, namely, addition and subtraction, etc. had been in practice. Vedic mathematics simplifies mathematical operations. Formulae and concepts of Vedic mathematics are widely accepted world over.

Vedic mathematics was an ancient method of solving mathematics problems. Later, Shankaracharya Swami Bharati Krishna Tirtha discovered Vedic mathematics. He is called the Father of Vedic mathematics.

**Here are some Vedic Maths Tricks**

- There are techniques for solving mathematical problems. This blog talks about addition and subtraction.
- These techniques are tricks resulting in efficiency and speed in solving mathematical problems. It ultimately leads to mental calculations. It consists of operations made repeated. Vedic mathematics tricks give answers in one step.
- Efficiency and ability for memorizing reduce calculations. Hence speed, time, money, and accuracy are not compromised.
- In ancient times, first mathematical operation was by counting from 1 and adding 1 further as below:

1 + 1 = 2,

2 + 1 = 3

3 + 1 = 4

……………

9 + 1 = 10 and further with multiple additions.

- Counting was done by use of fingers and other rude methods earlier.
- Over time, they became known and familiar results in memory. Thus, counting and adding existed. By repetition of these processes, again and again, we are familiar with most common numbers.
- The most basic arithmetic sequence is ‘Memorize and no need to calculate’.

**Basic sets to memorize**

1. All sums up to 10

Example |

2 + 4 = 6

3 + 5= 8

4 + 6 = 10

5 + 5 = 10

2. Addition of all single digit numbers.

Example |

5 + 5 = 10

6 + 7 = 13

7 + 7 = 14

9 + 8 = 17 etc.

3. All compositions of 10.

Example |

5 + ? = 10

6 + ? = 10

? + 6 = 10

**Additioin Tricks! Get better at calculations**

**Some special number pairs that add to 10**

Example |

1 + 9 = 10

2 + 8 = 10

3 + 7 = 10

4 + 6 = 10

5 + 5 = 10

Merely on seeing such pairs, the sum is understood mentally.

**Benchmarks**

To add one-digit number to another digit number, the technique involves having a basic number for easy calculation. To have multiples of 10 as benchmarks is safe and easy.

Example |

- 23 + 8. Take 20 as a benchmark. Then 23 + 8 = 20 + 3 + 8 = 20 +11 = 31.
- 126 + 8. Benchmark 130.

126 + 4 + 4 = 130 + 4 = 134.

**Breaking apart by place value**

Decimal place value system for every number is used.

Example |

14 + 77

= 10 + 4 + 70 + 7 = 10 + 70 + 4 + 7 = 80 + 11 = 91

42 + 66 = (40 + 2) + (60 + 6) = (40 + 60) + (2 + 6) = 100 + 8 = 108.

**Nature of additions**

**1. Additions are Commutative**

In sums for additions, the numbers can be rearranged or interchanged.

The result will be the same, even after the rearrangements.

Example |

8 + 3 = 3 + 8 = 11

6 + 41 = 41 + 6 = 47

22 + 63 = 63 + 22 = 85

Generalizing, a + b = b + a

Multiplication of numbers in a sum is also commutative.

(operations in subtraction and division are not commutative.

Example |

6 - 3 ≠ 3 - 6 and 6 ÷ 3 = 2 ≠ 3 ÷ 6 = 12

**2. Addition is Associative**

This is another law of addition.

As per this law, problems of additions with a greater number of additions, the items can be added in any order. The answer will not change.

Example |

(1 + 8) + 5 = 1 + (8 + 5) = 14

4 + (21 + 6) = (4 + 21) + 6 = 31

General rule:

a + (b + c) = (a + b) + c

**3. Partitioning and Reasoning **

When 1 is added to any positive number,

If the last digit is not 9, the last digit of the number is raised to the next higher number.

Example |

6897 + 1 = 6898

If all the digits are nines, except the first digit, replace them with zeros and raise the first digit to the next higher number.

Example |

6999 + 1 = 7000.

**Subtraction Tricks! Get better at calculations**

Subtraction is the opposite of the addition process. By going through the following examples, substitution can be learnt.

Subtraction is made easy and simple mathematical operation by Vedic mathematics.

1. Subtracting 1

10 - 1 =9

100 - 1 = 99

When subtracting 1 from zero, the answer contains only 9s.

2. Subtraction from power of 10

In this technique, we take the nearest power of 10 for the numbers involved and subtract the numbers from the base.

Another rule called Nikhilam rule helps us. Nikhilam is one of the 16 main Sutras of Vedic mathematics.

Nikhilam rule says, “All from 9 and the last from 10”.

Example |

10000-8675

99910 - 8675 =1325 Answer.

In this, we subtract each digit of the number simply from 9 for all digits except for the last digit, which is subtracted from 10.

If the number has a smaller number of digits, add leading zeros to have more digits.

Example |

100000-875 = 999910-00875

= 999910 - 00875

= 99125 Answer.

Example |

- Subtrahend is less than minuend.

3625 - 1789

Subtract the subtrahend from the highest next power of 10 by Nikhilam rule.

99910 - 1789 = 8211

Add the result to the minuend, i.e., 3625 + 8211 = 11836.

Deleting the first digit, 1, the answer is 1836.

- 4529 - 2380

In this, 2380, the last digit from the left is zero. Here ‘8’ is to be subtracted from 10, keeping the zero as the last digit from left.

Then,

99100 – 23 80 = 7620 + 4529

= 12149

Deleting the left first digit, the answer is 2149.

- 45827 - 398 (subtrahend is of less digits than minuend)

i.e., 45827 - 00398

i.e., 999910 - 00398 = 99602 ---------(1)

Add (1) with 45827

99602 + 45827 = 145429

Deleting 1, the answer is 45429.

- Minuend less than subtrahend

351 - 497

Apply NIKHILAM rule to Minuend

9910 - 351 = 649

Add subtrahend

649 + 497 = 1146

Deleting 1, first digit at left, the answer is -146.
