| 5000 | m | + | 5000 | ( | 1 | + | m | ) | ( | 1 | + | m | ) | = | 55000 |
| Left side of the equation = | 5000 | m | + | 5000 | × | 1 | ( | 1 | + | m | ) | + | 5000 | m | ( | 1 | + | m | ) |
| = | 5000 | m | + | 5000 | ( | 1 | + | m | ) | + | 5000 | m | ( | 1 | + | m | ) |
| = | 5000 | m | + | 5000 | × | 1 | + | 5000 | m | + | 5000 | m | ( | 1 | + | m | ) |
| = | 5000 | m | + | 5000 | + | 5000 | m | + | 5000 | m | ( | 1 | + | m | ) |
| = | 10000 | m | + | 5000 | + | 5000 | m | ( | 1 | + | m | ) |
