Answer 2

9)
a)(125 + 8) x 4 = 133 x 4 = 532
   286 + 234 x 5 = 286 + 1170 = 1456
b)(700 - 350) x 2 + 84 : 3 = 350 x 2 + 28 = 700 + 28 = 728
    230 + (87 : 3) + 242 x 3 = 230 + 29 + 726 = 259 + 726 = 985
c)350 - 6 x 18 : 3 + 184 x 2 = 350 - 108 : 3 + 368 = 350 - 36 + 368 = 314 + 368 = 682
  (250 x 2) : (100 : 10) + 550 = 500 : 10 + 550 = 50 + 550 = 600
Sper ca am inteles bine ce scrie la c).
