c) 38 + (66 - 6 x 10) =
d) 35 x (7 - 5) =
e) 52 - (25 + 78 : 13) =
f) (25 - 5 x 4) : 5 =

Answer 1

a) 76+81÷3-39=

76+27-39

103-39=64

b)52+36×4+32-90=

52+144-90=

196-90=106

c)38+(66-6×10)=

38+(66-60)=

38+6=44

d)35×(7-5)=

35×2=70

e)52-(25+78÷13)=

52-(25+6)=

52-31=21

f)(25-5×4)÷5=

(25-20)÷5=
