Question

giúp mih vs mih đang cần gấp lắm!!!!!

Answer 1

e: =(2004-2004)+(54-54)+(-15)=-15

f: =(-45789x2)-(357-57)=-91578-300=-91878

g: =(1259+1259)-(1409-1409)-12=2506

h: =(2750x2)-1229+438+29+438

=5500-1200+876

=5176

i: =-5+(-37+37)+(151+151)-45

=-50+302

=252

k: =(53-53)+(-145+145)-(359+259)=-618

Answer 2

e)2004-15+54-2004-54=(2004-2004)+(54-54)-15=-15

f)-45789-357-45789+57=(-45789-45789)-(357-57)=-91578-300=-91878

g)1259-1409-12+1259+140=(1259+1259)+(-1409+1409)-12=2518-12=2506

h)2750-1229+2750-(-438-29-438)=(2750+2750)-1229+438+29+438=5500-(1229-29)+(438+438)=5500-1200+876=5176

i)-5+-37-45+151--37=-5-37-45+151+37=(-5-45)+(-37+37)+151=-50+151=101

k)53-145-359-53+145-259=(53-53)+(-145+145)+(-359-259)=-618

l)-81-132-547+181-132-53=(-81+181)-(547+53)-(132+132)=100-600-264=-764

m)50-2016+50-118+2016-18=(50+50)+(-2016+2016)-(118+18)=100-136=-36
