Explanation :
The number is 9441. We need to create the highest number possible by moving only 2 matchsticks.
First, by moving the middle matchstick of the first "4" downwards, it will become a "1", making the number 91141.
Next, by moving the middle matchstick of the second "4" downwards in the same way, it will also become a "1", resulting in the highest number: 911111.
