Question

calculează repectând regulile învățate:a)9+4×

Answer 1

a) =9+4x[30+2x(4+15)-11]-3=
=9+4x(30+2x19-11)-3=
=9+4x(30+38-11)-3=
=9+4x57-3=
=9+228-3=
=237-3=
=234

b) =[160+12x9-(30-10)]x10
=(160+108-20)x10
=148x10
=1480

c) =6+6x[6+3x(6+26x1-24:8)]=
=6+6x[6+3x(6+26-3)]=
=6+6x(6+3x29)=
=6+6x(6+87)=
=6+6x93=
=6+558=
=564
