13 . 17 –256 : 16 + 14 : 7 – 1
= 221-256 : 16 + 14 : 7 – 1
= 221- 16+14 : 7 – 1
= 221-16+2-1
= 205+2-1
= 207-1
= 206
18 : 3 + 182 + 3.(51 : 17)
= 18 : 3 + 182 + 3.3
= 6 +182+3.3
= 6 + 182+9
= 188+9
= 197
15 – 25 .8 : (100 . 2)
= 15-25.8: 200
= 15- 200:200
= 15- 1
= 14
25 . 8 – 12.5 + 170 : 17 - 8
= 200-60+10-8
= 140 +10-8
= 150 - 8

27 . 75 + 25 . 27 - 150
= 27 . (75 + 25) - 150
= 27 . 100 - 150
