This document provides instructions for multiplying multi-digit numbers using the vertical and crosswise method. It explains how to multiply two 2-digit numbers with an example of 13 x 42. It then demonstrates multiplying two 3-digit numbers with the example 253 x 742. Finally, it notes that multiplying larger N-digit by N-digit numbers follows the same process, with the number of steps always being 2N-1, and provides contact information.

1. Faster Multiplication

2. Friends! This segment will help us in fast
multiplying N digit number by an another N digit
number.

3. The name of the method is
VERTICAL AND CROSSWISE METHOD.

4. First! We will start with Multiplication
of two Digit number by an another
two digit number.

5. Before going to calculation, I would like to
share an Animation that will help you in
multiplying a two digit by an another two digit
number.

7. Lets take for example
13
42
X

8. Now we will follow that animation and multiply 13
x 42.
Step 1 - First multiply 3 X 2, i.e. 6.
13
42
6

9. Step 2 - Multiply 1 X 2 and 3 X 4. Add the sum i.e.,
2 + 12 = 14. So write down 4 with carry 1.
13
42
14 6

10. Step 3 - Multiply 1 X 4 = 4 and 1 we have
previous carry, so the total became 5.
13
42
546

11. So, our final answer is 546.

12. 3 Digits X 3 Digits Multiplication

13. Friends! First have a look on Animation of a
3 digit X 3 digit multiplication.

15. Lets take for example
253
742
X

16. Now we will follow that animation and multiply
253 x 742.
Step 1 - First multiply 3 X 2, i.e. 6.
253
742
6

17. Step 2 - Now multiply 2 X 5 and 4 X 3 and add the
sum. So 10 +12 = 22. Now write down 2 with carry
2.
253
742
226

18. Step 3 - Now multiply 2 X 2, 3 X 7 and 5 X 4. So,
that give us 4 +21+20 = 45. Beside this, we have 2
as previous carry, so the total became 47.
253
742
4726

19. Step 4 – Now take last two digits of the problem.
Multiply 2 X 4 and 5 X 7 and add the sum up. That
give us 43. And, 4 we have previous carry so total
became 43 + 4 = 47.
253
742
47726

20. Step 5 – Finally, we take the last figure of the
problem. Simply multiply 2 X 7 = 14. And we have 4
as previous carry, so the total became 18.
253
742
187726

21. So, our final answer is 187726.

22. Now friends! Similarly the figure for
multiplication of 4 Digit X 4 Digit Number will be
like this :-

24. Now you can easily drive the figure for
multiplication of N Digit X N Digit number.
The formula for driving the number of steps is
( 2 X N ) – 1
where N is Number of digits.
