38 + 28 = 26 × 30 = 250 ÷ 5 = 530 - 250 =
50 × 51 = 636 ÷ 3 = 120 × 60 = 750 - 290 =
428 ÷ 2 = 20 × 47 = 560 ÷ 80 = 420 - 90 =
85 - 47 = 440 ÷ 11 = 27 + 63 = 180 + 470 =
35 × 200 = 360 - 190 = 30 × 48 = 660 ÷ 11 =
560 ÷ 14 = 320 × 8 = 800 ÷ 5 = 30 × 140 =
620 - 290 = 320 ÷ 20 = 900 ÷ 60 = 560 ÷ 14 =
740 ÷ 37 = 188 + 702 = 0 × 346 = 300 × 15 =
15 × 10 = 200 × 16 = 640 ÷ 80 = 330 ÷ 3 =
200 × 48 = 7600 ÷ 40 = 400 × 14 = 21 × 30 =
