Answer 1

a) 32:16+{76-2•[(20+4•5):5]-2•6}=

=2+{76-2•[(20+20):5]-12}=

=2+[76-2•(40:5)-12]=

=2+(76+2•8-12)=

=2+(76+16-12)=

=2+(92-12)=

=2+80=

=82

b) (3+6+9+12+15+18):(1+2+3+4+5+6)=

=63:21=

=3

c) 3+10•{3+10•[3+10•(3+10•3)-3]-3}-3=

=3+10•{3+10•[3+10•(3+30)-3]-3}-3=

=3+10•[3+10•(3+10•33-3)-3]-3=

=3+10•[3+10•(3+330-3)-3]-3=

=3+10•[3+10•(333-3)-3]-3=

=3+10•(3+10•330-3)-3=

=3+10•(3+3300-3)-3=

=3+10•(3303-3)-3=

=3+10•3300-3=

=3+33.000-3=

=33.003-3=

=33.000
