Nov 26, 2012 at 19:32 comment added Lior Bary-Soroker What about zeta functions? For example, if one wants to know how many points a variety has in a finite field $\mathbb{F}_p$, then he should study the zeta function of the variety which encodes the data of the number of points in every extension of $\mathbb{F}_p$.

Nov 26, 2012 at 4:42 comment added Minhyong Kim My favorite elementary example is the computation of $1+2+\cdots +n$, which is easier to do twice than once.

Nov 25, 2012 at 14:15 comment added Benjamin Steinberg Many examples of seemingly adding complexity are actually adding structure. The more structure an object has the easier it is to say something about it (in general). This is why $\mathbb Z$ is simpler than $\mathbb N$. This is also why Hilbert spaces are in some sense nicer to work with than untopologized infinite dimensional vector spaces.
