100
The top 0 has lots of friends so 0 goes over to the other 0’s house and they times each other. And 0 times any number is 0 so you put a 0 under the answer line.
Then the top 0 goes over to the bottom 1’s house and they times each other. And 0 times any number is 0 ( because if you have 0 of anything then you don’t have any) so you put a 0 under the answer line next to the 0 YOY put before so now you have 00
Then the top 1 goes over to the bottoms 1’s house and they times each other. And 1 times any thing is the other number ( because if you have 1 of anything then you don’t add anything)
So the you put a 1 by the 00
So your answer is 100!!!
