Multiplication Method - multiplying 2 numbers starting with same digit(s)

This vedic maths trick will help you in multiplying two numbers when these numbers start with the same digit. For example 34 x 37; see their ten's digit (starting digit) is same. Another example can be 234 x 232, see their hundred's and ten's digits (starting two digits) are same.

In one of the earlier post a similar method was described. In that like this trick the starting digit(s) should be same but at the same time the sum of digit at unit's place should be 10 – please check that out - Vedic multiplication

34 x 37

To multiply 34x37, we know they are in the base 30. Hence the reference point (base) will be 30.

Step 1.

Determine how much more is 34 from 30. The answer is 4

Determine how much more is 37 from 30. The answer is 7

Step 2.

Either add 4 to 37 = 41 or 7 to 34 = 41.

The result will be same always.

Step 3.

Multiply the resultant number from step 2 by the base, which is in this case 30

41x30 = 41x3x10 = 123x10 = 1230

Step 4.

Add to the resultant of step 3 the product of the numbers obtained from step 1. This will give you the answer.

1230+ (4x7) = 1230 + 28 = 1258

Another example,

23 x 29

From step 1 and step 2 above, 23 + 9 = 32 or 29 + 3 = 32

From step 3 : 32 x 20 = 640

From step 4 : 640 + (3x9) = 667

One more example,

234 x 232

From step 1 and step 2 above, 234 +2 = 236 or 232 + 4 = 236

From step 3 : 236 x 230 = 54280

From step 4 : 54280 + (4x2) = 54288

using the above method can also be used for multiplying two numbers close to humdred
