I'm going to buy a calculator. Can /prog/ recommend me anything outstanding in terms of what I can do with it, maybe having any defining features that makes it worth buying like being endorsed by the Sussman?
I'd quite like to program myself some games on there when I get bored in exams. I know at least some of /prog/ will be knowledgable on this subject.
In 1922, Adolf Fraenkel and Thoralf Skolem independently improved Zermelo's axiom system. The resulting 10 axiom system, now called Zermelo-Fraenkel axioms (ZF), is now the most commonly used system for axiomatic set theory.

The structure of a fractal object is reiterated in its magnifications. Fractals can be magnified indefinitely without losing their structure and becoming "smooth"; they have infinite perimeters—some with infinite, and others with finite surface areas.

Some basic sets of central importance are the empty set (the unique set containing no elements), the set of natural numbers, and the set of real numbers.

In set theory and its applications throughout mathematics, a class is a collection of sets (or sometimes other mathematical objects) which can be unambiguously defined by a property that all its members share.

The nature of the individual nonempty sets in the collection may make it possible to avoid the axiom of choice even for certain infinite collections. For example, suppose that each member of the collection X is a nonempty subset of the natural numbers.

For every non-empty set S there is a binary operation defined on S that makes it a group. (A cancellative binary operation is enough.)
