1. The problem is to perform the operation "oper wal dubara do," which translates to "do the operation again." Since the user did not specify the exact operation, let's assume a simple example: addition of two numbers, say 3 + 4. 2. First, perform the operation once: $$3 + 4 = 7$$. 3. Now, perform the operation again on the result and the same number 4: $$7 + 4 = 11$$. 4. Therefore, doing the operation again results in 11. If you meant a different operation, please specify it for a precise solution.
