= 30 x 100 + 300
= 3000 + 300
= 3300

100 + 200 - 4000 + 3000 + 100 - 200 + 300 =
100 + 200 - 4000 + 3000 + 100 - 200 + 300 = [(100+100)+(200-200)+(3000+300)]-4000
= [200+3300] -4000
= 3500-4000
= -500
ủng hộ mk nha mấy bn
âm 500 suy ra viết là: -500
X+100+100+200+500=3000-2000
x+100=3000
x + 100 = 3000
x = 3000 - 100
x = 2900
tk mk nha
100 . 2000-3000=?
100 . 2000 - 3000
= 200000 - 3000
= 197000
