| 方程左边 = | 2 | − | 6 | × | 3 | + | 6 | × | 8 | ( | 3 | + | 2 | x | ) |
| = | 2 | − | 18 | + | 48 | ( | 3 | + | 2 | x | ) |

| = | - | 16 | + | 48 | × | 3 | + | 48 | × | 2 | x |
| = | - | 16 | + | 144 | + | 96 | x |
| = | 128 | + | 96 | x |
| 128 | + | 96 | x | = | 8 | ( | 17 | x | + | 16 | ) |
| 方程右边 = | 8 | × | 17 | x | + | 8 | × | 16 |
| = | 136 | x | + | 128 |
| 128 | + | 96 | x | = | 136 | x | + | 128 |
| 96 | x | − | 136 | x | = | 128 | − | 128 |
| - | 40 | x | = | 128 | − | 128 |
| - | 40 | x | = | 0 |
| - | 0 | = | 40 | x |
| 40 | x | = | - | 0 |
| x | = | - | 0 | ÷ | 40 |
| = | - | 0 | × | 1 40 |
