Lời giải chi tiết:
6 – 3 – 1 = 2 | 1 + 3 + 2 = 6 | 6 – 1 – 2 = 3 |
6 – 3 – 2 = 1 | 3 + 1 + 2 = 6 | 6 – 1 – 3 = 2 |
6 – 3 – 1 = 2… | 1 + 3 + 2 = 6… | 6 – 1 – 2 = 3… |
6 – 3 – 2 = 1… | 3 + 1 + 2 = 6… | 6 – 1 – 3 = 2… |

1 + 3 + 2 = 6 6 - 3 -1 = 2 6 - 1 - 2 = 3
3 + 1 + 2 = 6 6 - 3 -2 = 1 6 - 1 - 3 = 2
1 + 3 + 2 =6 6 - 3 -1 =2 6 - 1 - 2 =3
3 + 1 + 2 = 6 6 - 3 -2 = 1 6 - 1 - 3 =2

Lời giải chi tiết:
5 + 4 = 9 | 6 + 3 = 9 | 7 + 2 = 9 | 1 + 8 = 9 |
5 + 3 + 1 = 9 | 6 + 2 + 1 = 9 | 7 + 1 + 1 = 9 | 1 + 2 + 6 = 9 |
5 + 2 + 2 = 9 | 6 + 3 + 0 = 9 | 7 + 0 + 2 = 9 | 1 + 5 + 3 = 9 |
5+4=9 | 6+3=9 | 7+2=9 | 1+8=9 |
5+3+1=9 | 6+2+1=9 | 7+1+1=9 | 1+2+6=9 |
5+2+2=9 | 6+3+0=9 | 7+0+2=9 | 1+5+3=9 |
