Vedic Maths – 4: General Method of Multiplication
From Archives
In our earlier articles, we have introduced you to the basics of Vedic Maths. We hope, by now, you are well-versed with them. We will now talk about the general method of multiplication. This method is useful when numbers are far apart in the number series and the choice of base (base method) can’t be made.
General Method of Multiplication
Example 1:
Multiply 34 by 86 (two digit number by two digit number)
Step 1:
Put the numbers one below the other, like this:
3 4
8 6
Here, we get only two columns since both of them are two digit numbers.
Step 2:
Now, multiply the digits in the first column (the first column is the one formed from the unit’s place of both the numbers).
4 X 6 = 24
Put 4 at the unit’s place of the answer (as shown below) while 2 is to be carried-over
3 4
X 8 6
—————————–
4 Carry-over = 2
Step 3:
Now cross-multiply both the columns, that is, multiply the digit at unit’s place of row 1 with the digit at ten’s place in row 2. Similarly, multiply the digit at ten’s place of row 1 with the digit at unit’s place of row 2, that is,
4 X 8 = 32
3 X 6 = 18
Add 32 and 18 (32 + 18 = 50)
Add the previous carry-over to 50, that is, 50 + 2 = 52
Put 2 at the ten’s place in the answer, 5 is the new carry-over
3 4
X 8 6
——————————
2 4 Carry-over = 5
Step 4:
Now, multiply the digits of the ten’s place column with each other, that is, 3 X 8 = 24
Add previous carry-over 5 to it
24 + 5 = 29
This 29 will be written as:
3 4
X 8 6
——————————————–
2 9 2 4
2924 is the answer
In our next segment, we will show you how to use the same method for 3-digit (or more) numbers. Till then, practice it well.
