The Flash is a superhero whose power is super speed. In the TV shows (the current one and the one from the 90s portrayed by John Wesley Shipp), the super speed effect is often shown by slowing down/freezing events around The Flash. This probably means that The Flash also has super-reflexes in addition to his super speed, so that he does not crash into the first building in his way.
What about The Flash's thinking ability? Since the world seems to slow down around him, I guess he can analyze a situation faster than anyone else (at least while in motion) but has The Flash ever been seen using "super fast thinking" to solve problems (like a super complicated maths equation or science problem)?
Note: I know The Flash mostly from the TV shows, but any answer from the comics is interesting to me too.
