Detailed Explanation: This is the general rule of multiplication of any three digit number by another three digit number.

For example, when we multiply 436 by 324; we first multiply 6 by 4, we get 24, so 4 is written and 2 is carry over.

Next we multiply 3 by 4, which is 12 and then 6 by 2, which is 12. We add 12, 12 and 2 (carry over), we get 26. 6 is written and 2 is carry over.

Then we multiply 4 by 4, which is 16; 6 by 3, which is 18 and then 3 by 2, which is 6. We add 16, 18, 6 and 2 (carry over), we get 42. 2 is written and 4 is carry over.

Again, we multiply 4 by 2, which is 8 and then 3 by 3, which is 9. We add 8, 9 and 4 (carry over), we get 21. 1 is written and 2 is carry over.

Lastly, we multiply 4 by 3, which is 12 and we add 12 and 2, which is 14. So, 14₂1₄2₂6₂4 is the answer.
