Răspuns:
o luăm pe bucăți
1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 = 2
1 x 73 =73
2-73 = -71
-71-12= -83
456.456.735 : 2 = 228.228.376,5
-83 +228.228.376,5 = 228.228.293,5
1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 x 73 - 12 + 456.456.735 : 2= =228.228.293,5
