Multiplication of a 2 figure integer by another 2 figures integer :

For Example, 12 × 23 = ( 1×2 ) | ( 1×3 + 2×2 ) | ( 3×2 ) = 276

or in base 10:

of course, the cases where or are to be considered.

Let us take the above example in another way. While multiplying 2 digit numbers with each other,

- Step 1: the product of the last digits in both numbers becomes the last digit of the result. Therefore the last digit of the result is 2*3=6
- Step 2: the first digit of the first number is multiplied with the second digit of the second number i.e.1*3=3. Now,the last digit of the first number is multiplied with the first digit of the second number i.e.
- 2*2=4. Both these numbers are now added
- 3+4=7. This becomes the second digit of the result

- Step 3: The first digit of the product is obtained by multiplying the first digits of both numbers, i.e. 1*2=2

Our final answer is 276.
