| ( | 29 | + | m | ) | ( | 22 | + | m | ) | = | 5 | ÷ | 4 | × | 29 | × | 22 |
| Left side of the equation = | 29 | ( | 22 | + | m | ) | + | m | ( | 22 | + | m | ) |
| = | 29 | × | 22 | + | 29 | m | + | m | ( | 22 | + | m | ) |
| = | 638 | + | 29 | m | + | m | ( | 22 | + | m | ) |
| = | 638 | + | 29 | m | + | m | × | 22 | + | m | m |
| = | 638 | + | 51 | m | + | m | m |
| 638 | + | 51 | m | + | m | m | = | 5 | ÷ | 4 | × | 29 | × | 22 |
| Right side of the equation = | 1595 2 |
| 638 | + | 51 | m | + | m | m | = | 1595 2 |
