Multiply Two Numbers using Vedic Maths Base Method
Rules:
Rule 1. Subtract both the numbers from the base value.
Rule 2. Cross section the multiplier and multiplicand value and add it with the reduced result. You should get same value on both the sides.
Rule 3. Multiply the reduced values. If the obtained value is greater than the base value, carry the remainder.
Rule 4. Subtract the remainder value from the difference value and find complement for the reduced result. If you get the carry value again, subtract the one from the difference value.
Rule 5. Join the obtained value to get the final result.
Multiplication of Numbers Above and Below Base 100
Example 1 : 92 X 111

Here base value is 100
Rule 1 : 92 – 100 = - 8 ; 111 – 100 = 11,
Rule 2 : 92 + 11 = 103 ; 111 – 8 = 103
Rule 3 : 8 x 11 = 88
Rule 4 : 103 - 1 = 102 Complement of 88 is 12 (100 - 88 = 12)
Rule 5 : Join the values, , 92 X 111 = 10212.
Multiplication of Numbers Above and Below Base 1000
Example II : 985 X 1099

Here base value is 1000
Rule 1 : 985 – 1000 = -15 ; 1099 – 1000 = 99,
Rule 2 : 985 + 99 = 1084 ; 1099 - 15 = 1084
Rule 3 : 15 x 99 = 1485. 15 x 99 = 1485. Here the obtained value is greater than one. Carry the remainder 1.
Rule 4 : 1084 - 1 = 1083. Now again subtract the one from the difference value because we have the carry value one. So the result wil be 1082. Complement of 1485 is 515.(2000 – 1485 = 515)
Rule 5 : Append the resultant values, 985 X 1099 = 1082515
Thus, the vedic maths base method multiplication can be used for faster multiplication.

Multiplication of Numbers Below the Base Number

Rules:
Rule 1. Reduce numbers from the base values.
Rule 2. Cross section the multiplier and multiplicand and add it to the reduced values. You will get same difference on both the sides.
Rule 3. Multiply the reduced values. If the resultant value is less than the base value add zero before it. If the resultant value is greater than the base value carry the remainder 1.
Rule 4. Add the carry value with the difference value.
Rule 5. Append both the values to get the final result.
Example I : 89 X 98
Rule 1 : Here base value is 100. So, 89 - 100 = -11 and 98 - 100 = -2
Rule 2 : 89 – 2 = 87 ; 98 -11 = 87
Rule 3 : -2 x -11 = 22
Rule 4 : No carry values
Rule 5 : Append the result is, 89 x 98 = 8722
Example II : 928 X 986
Rule 1 : Here base value is 1000. So, 928 - 1000 = -72 and 986 - 1000 = -14
Rule 2 : 928 - 14 = 986 - 72 = 914
Rule 3 : 14 x 72 = 1008. Here the obtained value is greater than the base value. So carry the one. i.e., 008 (carry 1)
Rule 4 : 914 + 1 = 915
Rule 5 : Append the obtained values, 928 x 986 = 915008

Thus, the vedic maths multiplication for numbers below the base numbers can be done easier.
