The error bars on solving a math problem (or writing a program, or anything else) are not infinite unless you make the mistake of stretching them to the point of encompassing absolute certainty that a solution is found. Almost no software development task is like proving or disproving P=NP: often, they are like homework problems. And, like uninspired homework problems, it is often a matter of grinding through a process with all due attention to the details.
