SUMMARY
The forum discussion centers on proving the equation $$\sum_{i=1}^{n}\frac{1}{i(i+1)}=1-\frac{1}{(n+1)}$$ using mathematical induction. The user initially struggled to manipulate the expression to reach the desired form of $$1-\frac{1}{k+2}$$. The breakthrough came when the user realized that separating the fraction $$\frac{1}{i(i+1)}$$ into $$\frac{1}{i} - \frac{1}{i+1}$$ simplifies the proof process significantly.
