Math Puzzle 1.
Place 6 checkers on a table in a row, alternating them black, white, black, white, and so on as shown.
Leave a vacant place large enough for 4 checkers on the left.
Move the checkers so that all the white ones will end on the left, followed by all the black ones.
The checkers must be moved in pairs, taking 2 adjacent checkers at a time, withouth switching their order, and sliding them to a vacant place.
To solve this problem, only 3 such moves are necessary.
Have fun ! :)
