After basic algebra and arithmetic, the fields of mathematics actually branch out. Branches which seem "high" based on their traditional university course numbers might actually be more accessible than those numberings suggest. Fields like game theory and graph theory, for example, do not actually require calculus, though they are numbered much higher than calculus is. Nonetheless, there are unexpected connections between even the most disparate-seeming areas. Theorems in complex analysis are used to answer questions in number theory where there's no obvious connection to the complex numbers. Results in computability theory have startling consequences in real analysis which don't, at first glance, have the remotest relation to the former.
