Answer 1

50625-25+1111=51711
(104+25)x3-300=129x3-300=387-300=87
65+8x(101+111)=65+8x212=65+1696=1761
30+(60-6x(7+4)-6)=
30+(60-6x11-6)=
30+(60-66-6)=
30+(-12)=
30-12=18

Answer 2

a).  50625-625:25+101×11=51711
      =50625-25+1111=
      =50600+1111=
       =51711

b).(208:2+50:2)×3-75×4=87
    =(104+25)x3-300
    =129 x 3 -300 =
     =387-300=
       =87

c). 65+8×(101×1+111:1)=1761
     =65 + 8 x(101 +111)
     = 65 +8 x 212
      =65 +1696
     = 1761

d). 30+[60-6×(63:9+36:9)-6]= 18 
    =30+[ 60 -6 x (7 +4) -6]=
    = 30+ (60-6 x 11 -6)=
    =30 + (60- 66 - 6 ) =
    = 30 + ( - 6 - 6 ) =
    = 30 - 12 =
    = 18
