Ajutor . Am mai scris odata dar vad xa nimeni nu ma baga in seama . Eu sunt singura care trebuie sa astepte 5 ore

1). 300-30x[30+3x(940-140x6):10:3]:10=
= 300-30x[30+3x(940-840):10:3]:10=
= 300-30x(30+3x100:10:3):10=
= 300-30x(30+300:10:3):10=
= 300-30x(30+30:3):10=
= 300-30x(30+10):10=
= 300-30x40:10=
= 300-1200:10=
= 300-120=
=180


2). 100x[19x19:361+3x(3+9)-(12-9:3)]+7x6:7:2=
=100x[ 361:361+3x12-(12-3)]+42:7:2=
=100x(1+36-9)+6:2=
=100x(37-9)+3=
=100x28+3=
=2800+3=
=2803

Sper ca te-am ajutat!! :))
