Answer 1

I) (700+35):15+(225-81):12 =
=735:15+144:12 =
=49+12=61

j) (270+57x10):14-85:17=
= (270+570):14-5=
=840:14+5=
=60+5=65

k) 85-(36+2x17):14=
= 85-(36+34):14=
= 85-70:14=
=85-5=80

l) 1305:29-21x(36:6-4)=
=45-21x(6-4)=
=45-21x2=
=45-42=3

m) 25x14-(72:9+15x3):53x350=
=350-(8+45):53x350=
=350-53:53x350=
=350-1x350=
=350-350=0

n) 31x(256:14-0:72)-3x41=
=31x18,(285714)-3x41=
=566,(857142)-123=443,(857142)
(probabil exercitiul e scris gresit)

o) 255:(18+49:7)-368:46 =
= 255:(18+7)-8 =
= 255:25-8 =
=10,2-8=2,2

p)184x(448-16x28)+7x(83-2x19)=
=184x(448-3648)+7x(83-38)=
=184x(-3200)+7x45=
=-588800+315=
=-588485
