Answer 1

8+{7+[10+(8-x:2):3]:4}:5=10
7+[10+(8-x:2):4=10.5-8
10+(8-x:2):4=42-7
(8-x:2)=35.4
8-x:2=140
8-x=140.2
8-x=280
-x=280-8
-x= 272
x= -272

Answer 2

a)54-54:3+{2x[2+(108-100):4]}+270:10=
=54-54:3+[2x(2+8:4)+270:10=
=54-54:3+(2x4)+270:10=
=54-54:3+8+27
=54-18+8+27=
=36+8+27=
=71
b)2x{2+[1002-4x(9:3x3-8x4:4)]}:100=
2x{2+[1002-4x(9-8)]}:100=
=2x[2+(1002-4x1)]:100=
=2x[2+(1002-4)]:100=
=2x(2+998):100=
=2x1000:100=
=2000:100=
=20
c)15-4x{95-5x[36-30:(25-6x4)]-32}:11=
=15-4x{95-5x[36-30:(25-24)]-32}:11=
=15-4x[95-5x(36-30:1)-32]:11=
=15-4x[95-5x(36-30)-32]:11=
=15-4x(95-5x6-32):11=
=15-4x(95-30-32):11=
=15-4x(65-32):11=
