This is part of the number system, including all the positive integers from 1 to infinity.

It is defined as a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

What do you call the enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.

It is a set which contains all the elements or objects of other sets, including its own elements.

It refers to a number written in a certain order and used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.

It is a steppingstone on the path to proving a theorem. A minor result whose sole purpose is to help in proving a theorem.

He is the Father of Logic.

It is a one-to-one correspondence (mapping) between two sets that preserves binary relationships between elements of the sets.

It is defined as numbers that have real and imaginary numbers. This is also defined as real number whose imaginary part is 0.

He is a mathematician who is most widely known for development of non-standard analysis, a mathematically rigorous system whereby infinitesimal and infinite numbers were reincorporated into modern mathematics.

These are a generalization of the natural numbers used to measure the cardinality of sets.

This word comes from a 17th-century Modern Latin coinage infinitesimus, which originally referred to the "infinity-th" item in a sequence.

What do you call to a mathematical statement or property considered to be self-evidently true, but yet cannot be proven?

What is Godel's Theorem called?
