Question

Efectueaza:100:(6+4)+2x(25+10)
72:9x(20-3x5)
80-5x(8-30:5)
6+6:(8-6)+8x6-7
NU DOAR RZULTATUL SI EFECTUAREA,DAU COROANA

Answer 1

100:(6+4)+2x(25+10)=
100:10+2x35=
10+70=80
........................................
72:9x(20-3x5)=
8x(20-15)=
8x5=40
.........................................
80-5x(8-30:6)=
80-5x(8-6)=
80-5x2=
80-10=70
........................................
6+6:(8-6)+8x6-7=
6+6:2+48-7=
6+3+48-7=
9+48-7=
57-7=50

Answer 2

=100:10+2x35
=10+70=
=80
............................
 
=8x(20-15)
=8x5
=40
.............................
 
=80-5x(8-6)
=80-5x2
=80-10
=70
............................

=6+6:2+48-7
=6+3+48-7
=9+48-7
=57-7
=50
