One thought on “Премести едно шкорче, за да биде точно равенството:”
1 matchstick at number 7 was moved to 9 and became 8.
Thus, the number of matches in the number 8 becomes 7.
The number of matches in number 1 is 2.
The number of matches in the number 5 is 5.
The process is done with the number of matchsticks.
7-2 = 5
