1) 294 - 167= 127

14 - 7 = 7

80 - 60 = 20

200 - 100 = 100

7 + 20 + 100 = 127

      7 14

2) 384 - 158 = 226

14 - 8 = 6

70 - 50 = 20

300 - 100 = 200

6 + 20 + 200 = 226

   6 15 13

3) 763 - 477 = 286

13 - 7 = 6

150 - 70 = 80

600 - 400 = 200

6 + 80 + 200 = 286

     7 14 13

4) 853 - 367 = 486

13 - 7 = 6

140 - 60 = 80

700 - 300 = 400

6 + 80 + 400 = 486
