( | 1 100 | − | 1 100 | ) | ( | 1 100 | − | B | ) | = | B |
Left side of the equation = | 1 100 | ( | 1 100 | − | B | ) | − | 1 100 | ( | 1 100 | − | B | ) |
= | 1 100 | × | 1 100 | − | 1 100 | B | − | 1 100 | ( | 1 100 | − | B | ) |
= | 1 10000 | − | 1 100 | B | − | 1 100 | ( | 1 100 | − | B | ) |
= | 1 10000 | − | 1 100 | B | − | 1 100 | × | 1 100 | + | 1 100 | B |
= | 1 10000 | − | 1 100 | B | − | 1 10000 | + | 1 100 | B |
= | 0 | − | 0 | B |
0 | − | 0 | B | = | B |
- | B | = | 0 |
- | 0 | = | B |
B | = | - | 0 |
