Ủng hộ tui nhé! ^.^ 

=(12+88) +(34+46)*2+(55+65)=100+2*80+120=100+160+120=380

kết quả là 380

12 + 34 + 88 + 46 + 55 + 34 + 65 + 46

= (12 + 88) + (34 + 46) + ( 55 + 65) + ( 34 + 46)
= 100 + 80 + 120 + 80

= 380

36x4=144

a) (12-46)+(46+88)

= 12-46+46+88

= (12+88)+[(-46)+46]

= 100+0

=100.

b) (14+67)+(33-14+100)

= 14+67+33-14+100

=[ [14+(-14)]+[(67+33)+100]

= 0+200

= 200.

c) (35+12-47)-(12+53+65)

= 35+12-47-12-53-65

=[12+(-12)]+[(-47)+(-53)]+[35+(-65)]

=0+(-100)+(-30)

=(-100)+(-30)

=-130.

Chúc bạn học tốt !!!

a) (12-46)+(46+88)=12-46+46+88

=(12+88)-(46-46)=100

b) (14+67)+(33-14+100)=14+67+33-14+100

=(14-14)+100+(67+33)=100+100=200

c) (35+12-47)-(12+53+65)=35+12-47-12-53-65

=(12-12)-(47+53)-(65-35)= -100-30

=-130

=200

tk tớ nhé

=(12+88)+(36+64)

=100+100

=200

k mình nha

(12+88)+(36+64)=100+100=200

= (12+88)+(36+64)

=100+100=200

12+88+36+64

=[12+88] + [36+64]

=100 + 100
