Answer 1

a) 35 – 3.7 + 9.2² =

35 - 21 + 9.4 =

35 - 21 + 36 =

14 + 36 =

50

b) 9 - 5.14.2 + 323 =

9 - 70.2 + 323 =

9 - 140 + 323 =

-131 + 323 =

192

c) 2³.4² - 7² - 140/5 =

8.16 - 49 - 140/5 =

8.16 - 49 - 28 =

144 - 49 - 28 =

144 - 77 =

67

d) 8.8 – 8² =

8² - 8² =

64 - 64 =

0

e) 340 : (48 – 14) + 18 – 3² =

340 : 34 + 18 - 9 =

10 + 18 - 9 =

28 - 9 =

19

f) (28 – 7.4).(3976:14.19) =

(28-28).(284.19) =

0 . 5396 =

0
