| 2 | ( | ( | 4 | + | 4 | p | ) | ( | 4 | + | 4 | p | ) | ) | = | 16 | p |
| Left side of the equation = | 2 | ( | 4 | + | 4 | p | ) | ( | 4 | + | 4 | p | ) |
| = | 2 | × | 4 | ( | 4 | + | 4 | p | ) | + | 2 | × | 4 | p | ( | 4 | + | 4 | p | ) |
| = | 8 | ( | 4 | + | 4 | p | ) | + | 8 | p | ( | 4 | + | 4 | p | ) |
| = | 8 | × | 4 | + | 8 | × | 4 | p | + | 8 | p | ( | 4 | + | 4 | p | ) |
| = | 32 | + | 32 | p | + | 8 | p | ( | 4 | + | 4 | p | ) |
| = | 32 | + | 32 | p | + | 8 | p | × | 4 | + | 8 | p | × | 4 | p |
| = | 32 | + | 32 | p | + | 32 | p | + | 32 | p | p |
| = | 32 | + | 64 | p | + | 32 | p | p |
| 32 | + | 64 | p | + | 32 | p | p | = | 16 | p |
