2 + 6 = 20
3 + 5 = 12
4 + 8 = 30
Vậy: 6 + 9 =
2=6
3=12
4=20
5=30
6=42
9=???????????
Nếu:
2 = 6
3 = 12
4 = 20
5 = 30
6 = 42
9 = ??
Nếu :
2=6
3=12
4=20
5=30
6=42
Thì : 9=??
1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30=

100+90+80+70+60+50+40+30+20+10+1+2+3+4+5+6+7+8+9=
tính 1*2*3*4*5*6*7*8*9*10*11*12*13*14*15*16*17*18*19*0*20*21*22*23*24*25*26*27*28*29*30*31*32
ai nhanh mình tích cho
11+12+13+14+15+16+17+18+19=
10+20+30+40+50+60+70+80+90=
1+2+3+4+5+6+7+8+9=
