Answer 2

r) 21:[16-(1+2•6)]•[12-(4+14:2)]:7=

=21:[16-(1+12)]•[12-(4+7)]:7=

=21:(16-13)•(12-11):7=

=21:3•1:7=

=7:7=1

s)(270-4•10):5+36•8-(700-350):5=

=(270-40):5+36•8-350:5=

=230:5+288-70=

=46+288-70=

=334-70=

=264

t)477•6+2•[72:8+5•160-(4•200:2-44:3)=

=477•6+2•[72:8+5•160-(400-15)]=

=477•6+2•(9+800-385)=

=477•6+2•(809-385)=

=2862+2•464=

=2862+848=

=3710

u)10.000-4•2•[(59-75:3•2):9+29]:10=

=10.000-4•2•[(59-25•2):9+29]:10=

=10.000-4•2[(59-50):9+29]:10=

=10.000-4+2•(9:9+29):10=

=10.000-4+2•(1+29):10=

=10.000-4+2•30:10=

=10.000-4+60:10=

=10.000-4+6=

=9996+6=

=10002
