Answer 1

197 825:25-7900+(100-9•9)-31=

= 197 825:25-7900+(100-81)-31 =

= 197 825:25-7900+19-31 =

= 7913-7900+19-31 =

= 13-12 =

= 1

(1966-777-88)•28+285:15 =

= 1101•28+19 =

= 30 828+19 =

= 30 847

[2093+15 236:13-(101-96)]:10+101 =

= (2093+ 15 236:13-5):10+101 =

= (2093+1172-5):10+101 =

= 3260:10+101 =

= 326+101 =

= 427

[(263•61+57):100+183]:2+90 =

= [(16 043+57):100+183]:2+90 =

= (16100:100+183):2+90 =

= (161+183):2+90 =

= 344:2+90 =

= 172+90 =
