34+35+36+37-14-15-16-17
=\(\left(34-14\right)\)+\(\left(35-15\right)\)+\(\left(36-16\right)\)+\(\left(37-17\right)\)
=20+20+20+20
=80
34+35+36+37-14-15-16-17
=(34-14)+(35-15)+(36-16)+(37-17)
=20+20+20+20
=80
=80 nha bn
chuc bn hoc tot
happy new year
34+35+36+37-14-15-16-17
= 34+35+36+37+(-14)+(-15)+(-16)+(-17)
=[34+(-14)]+[35+(-15)]+[36+(-16)]+[37+(-17)]
= 20+20+20+20=20.4=80
