VA ROG AJUTATIMA DAU CORONITA

Answer 1

a) 248:4:2x7+[(159+279):6-(832-759)]x129 =
217+[438:6-73]x129=
217+0x129=
217+0=217

b) 39x[45x8:5:9x(1.348-1.299):7]-2.184 =
39x[8x49:7]-2184=
39x56-2184=2184-2184=0

c) 1.000:100x[1.000.000-(315x3:9+986.428)] =
10x[1000000-(105+986428)]=
10x[1000000-986533]=
10x13467=134670

d) (78:6x87)+[131-(29x35-278)x0]-31x2 =
1131+[131-(1015-278)x0]-62=
1131+[131-737x0]-62=
1131+131-62=1200

e) 219x36-(132:6+38x7)x24+[(105+80):5+8]:5 =
7884-(22+266)x24+[185:5+8]:5=
7884-288x24+45:5=
7884-6912+9=981
