Answer 1

Răspuns:

a) (4038:24+11328:48)=404

4036:24=168

11328:48=236

168+236=404

{9+[8×404:32]}:10=

404×8=3232

3232:32=101

{9+101}:10=

9+101=110

110:10=11

b). (595-135×2-38×3)×2=270

135×2=270

38×3=114

595-270-114=211

211×2=422

[700-422]-100=178

700-422=278

278-100=178

e). (77:7-63:9)=

77:7=11

63:9=7

11-7=4

900-[484:4]×5=295

484:4=121

121×5=605

900-605=295

D. (24×8000-190000)=

24×8000=192000

192000-190000=2000

[2000:1000×63-36]:45=

2000:1000=2

2×63-36=

2×63=126

126-36=90
