As you can see in the picture, 20 matchsticks have been used to form five squares. What you have to do is move two of the matchsticks in a manner that seven squares are formed.Please note that you cannot overlap the matches or break them. The squares can be on any size but they must be closed squares.
As you can see in the picture, we have just moved two of the matchsticks and now we have seven squares of 1x1, 2x2 and 3x3 sizes.
