**Vedic mathematics** is a system of mathematics consisting of a list of 16 basic sūtras, or aphorisms. They were presented by a Hindu scholar and mathematician, Bharati Krishna Tirthaji Maharaja, (He was also the Shankaracharya of Govardhan Math, Puri, from 1925 until he passed away in 1960.)

Tirthaji claimed that he found the sutras after years of studying the Vedas.

In the first lesson of Vedic Maths, let's understand:

**Multiplication by 5**

Instead of multiplying a number by 5, it's better to multiply it by 10 first, and then divide the result by 2. For example, 235x5=2350/2=1175

Same way, you can, multiply by 50 also.

**Multiplication by 4**

The method says, replace it with a repeated operation by 2 eg. 124x4=248x2=4

**Multiplication by 25**

Multiply first by 100 and then you can divide by 4. eg. 37x25=3700/4=1850/2=925.

**Multiplication by 8**

You can replace with a repeated operation by 2. For example 124x8=248x4=496x2=992.

**Multiplication by 45**

Multiply first by 90 and then divide the result by 2. For example 37x45=37x90/2=3330/2=1665

Or put into use , this method 37 x45 = 37 (100/2 -10/2)= 3700/2-370/2=1850-185=1665

**Multiplication by 55**

Multiply first by 110and then divide by 2. For example37x55=37x110/2=4070/2=2035

**Multiplication by 75**

Multiply first by 300 and then divide by 4 .For example37x75=37x300/4=11100/4=2775

**Multiplication by 125**

Multiply first by 500 and then divide by 4 For example37x125=37x500/4=18500/4=4625

**Multiplication by 150**

Multiply first by 300 and then divide by 2 For example37x150=37x300/4=11100/2=5550**Multiplication by 175**

Multiply first by 700 and then divide by 4 For example37x175=37x700/4=25900/4=6475

**Multiplication by 225**

Multiply first by 900 and then divide by 4 For example37x225=37x900/4=33300/4=8325

**Multiplication by 275**

Multiply first by 1100 and then divide by 4

For example37x275=37x1100/4=40700/4=10175
