Question

efectueaza respectand ordinea operatiilor: 176+(100-78)x19-16x(29+-48)= ; 1000-(7x6x13-477)x12+25x(60-4x9)= : (39x23-25x19)+(800+26x38-19x34)= ?

Answer 1

176+(100-78)x19-16x[29+(-48)]=
176+22x19-16x(-19)=
176+418-(-304)=
176+418+304=
594+304=
=898 

1000-(7x6x13-477)x12+25x(60-4x9)=
1000-(546-477)x12+25x(60-45)=
1000-69x12+25x15=
1000-828+375=
172+375=
=547 

(39x23-25x19)+(800+26x38-19x34)= 
(897-475)+(800+988-646)=
422+(1788-646)=
422+1142=
=1564   



 Sper ca te-am ajutat ! :)
