Detailed Explanation: This is the general rule of multiplication of any four digits number by a two digits number.

For example, when we multiply 2436 by 23; we first multiply 6 by 3, we get 18, so 8 is written and 1 is carry over.

Next we multiply 3 by 3, which is 12 and then 6 by 2, which is 12. We add 9, 12 and 1 (carry over), we get 22. 2 is written and 2 is carry over.

Again, we multiply 4 by 3, which is 12 and then 3 by 2, which is 6. We add 12, 6 and 2 (carry over), we get 20. 0 is written and 2 is carry over.

Again, we multiply 2 by 3, which is 6 and then 4 by 2, which is 8. We add 6, 8 and 2 (carry over), we get 16. 6 is written and 1 is carry over.

Lastly, we multiply 2 by 2, which is 4 and add 4 and 1, which is 5. So, 56028 is the answer.
