Solution:

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

For example, when we multiply 36 by 27; we first multiply 6 by 7, we get 42, so 2 is written and 4 is carry over.

Next we multiply 3 by 7, which is 21 and then 6 by 2, which is 12. We add 21, 12 and 4 (carry over), we get 37. 7 is written and 3 is carry over.

Lastly, we multiply 3 by 2, which is 6 and add 6 and 3, which is 9. So, 972 is the answer.
