Question

Efectuati respectand ordinea operatiilor:
[ 328 x 1 + (7 + 7 x 27 - 9 x 21 + 195 : 5 ) ] : 100 =
[ 918 : 9 - ( 448 : 8 - 306 : 6 ) ] x 9 [ 9 + ( 7 x 9 - 3 x 9 ) ] =
2783 x 0 + 36 : 1 - 0 : 7 - 36 x 1 =

Answer 1

[328*1+(7+7*27-9*21+195:5)]:100=
[328*1+(7+189-9*21+195:5)]:100=
[328*1+(7+189-189+195:5)]:100=
[328*1+(7+189-189+39)]:100=
[328*1+(7+0+39)]:100=
[328*1+(7+39)]:100=
(328*1+46):100=
(328+46):100=
374:100=187/50 =3.74

[918:9-(448:8-306:6)]*9[9+(7*9-3*9)]=
[918:9-(56-306:6)]*9[9+(7*9-3*9)]=
[918:9-(56-51)]*9[9+(7*9-3*9)]=
[918:9-(56-51)]*9[9+(63-3*9)]=
[918:9-(56-51)]*9[9+(63-27)]=
(918:9-5)*9(9+36)=
(102-5)*9(9+36)=
97*9(9+36)=
97*9*45=
873*45=39285

2783*0+36:1-0:7-36*1=
0+36-0-36=0-0+36-36=0
