If you see the picture attached with this question, you can find four 1x1 and one 3x3 squares. Twenty matchsticks have been used to create this figure. Now you have to move two matchsticks anywhere so that there are seven resulting squares. The size of the squares does not matter. But you cannot break the matchsticks and you cannot overlap them.

How will you do it?

By moving 4 match sticks, can you create 9 squares instead of 7.

Which maximum three digit number can you form by adding exactly 3 matches?

Can you move three matchsticks to form three triangles?
