a. 5386 - 3258 = 5000 + 300 + 70 + 16 - Numerele trebuie scazute
3000 + 200 + 50 + 8
---------------------------------------------
2000 + 100 + 20 + 8 = 2128
b. 7328 - 4152 = 7000 + 200 + 120 + 8 -
4000 + 100 + 50 + 2
------------------------------------------
3000 + 100 + 80 + 6 = 3186
c. 8267 - 5434 = 7000 + 1200 + 60 + 7 -
5000 + 400 + 30 + 4
-----------------------------------------------
2000 + 800 + 30 + 3 = 2833
