100-20-20+50+60-70-100+90-80-10=?
ai giải nhanh nhất mình tich cho!
10 -20 = 80 - 20 = 60 + 50 = 110 + 60 = 170 - 70 = 100 - 100 = 0 + 90 = 90 - 80 = 10 - 10 = 0
đáp số : 0

hok tốt
10+20+30+40+50+60+70+80+90+100=???????????????????????????????????????????
10 + 20 + 30 + 40 + 50 + 60 + 70 + 80 + 90 + 100 = 550
Chúc bạn học tốt nhé !
10+20+30+40+50+60+70+80+90+100=(10+90)+(20+80)+(30+70)+(40+60)+50+100=100+100+100+100+50+100=(100+100+100+100+100)+50=500+50=550
10+20+30+40+50+60+70+80+90+100=
=10+90+20+80+30+70+40+60+50+100
=100+100+100+100+50+100
=550
10 + 20 + 30 + 40 + 50 + 60+ 70 + 80 + 90 + 100 = 550
10+20+30+40+50+60+70+80+90+100=?
= 10 x ( 1 + 2 + 3 + 5 + 6 + 7 + 8 + 9 + 10)
= 10 x 45
= 450
10+20+30+40+50+60+70+80+90+100
=(100+10)+(90+20)+(80+30)+(70+40)+(60+50)
=110+110+110+110+110
=110x5=550
Đúng 100% đấy !
=10x(1+2+3+4+5+6+7+8+9+10)
=10x45
=450
Đúng 100% đấy! Vừa nãy là em mình làm nên cho mình sorry!
10+20+30+40+50+60+70+80+90+100=..................
10+20+30+40+50+60+70+80+90+100=(10+100)+(20+90)+(30+80)+(40+70)+(50+60)
=110+110+110+110+110
=110x5
=550
= ( 10 + 100 ) + ( 20 + 90 ) + ( 30 + 80 ) + ( 40 + 70 ) + ( 50 + 60 )
= ( 10 + 100 ) x 5
= 110 x 5
= 550
