Question

[6+6×(6+6×6)÷6+6×(6-6)×(6+6:6)]÷8

Answer 1

Ordinea efectuarii operatiilor:intai ne ocupam de parantezele rotunde apoi cele patrate, mai intai efectuam inmultirea/impartirea apoi adunarea/scaderea:
[6+6×(6+6×6)÷6+6×(6-6)×(6+6÷6)]÷8=
=[6+6×(6+36)÷6+6×0×(6+1)]÷8
=[6+6×42÷6+0]÷8
=[6+42]÷8
=48÷8
=6

Answer 2

[6+6x(6+6x6):6+6x(6-6)x(6+6:6)]:8=
[6+6x(6+36):6+6x0x(6+1)]:8=
[6+6x42:6+0]:8=
[6+6x7]:8=
(6+42):8=48:8=6
