Answer 1

Răspuns:

170

Explicație pas cu pas:

$2 \times (90 \div 2 + (60 - 20)) \times 1 \\ 2 \times (90 \div 2 + 40) \times 1 \\ 2 \times (45 + 40) \times 1 \\ 2 \times 85 \times 1 \\ 170$

Answer 2

2×[90:3+(120:4-20)]×1=

=2×(90:3+10)×1=

=2×40×1=

=80

2007+18:[2+(16-108:27):3]=

=2007+18:(2+11:3)=

=2007+18:(2+3,6)=

=2007+18:5,6=

=2007+23,6=
