The term math successor is used in set theory. Set theory is a branch of mathematics that involves the relationship and nature of sets, or collections of objects. It's technically possible for any item to be collected into a set (for example, stamps or baseball cards). However, the term "set theory" is usually applied to sets that are mathematical in nature (for example, sets of numbers).
According to Eric Weisstein, author of "Successor," a math successor is defined as "for any ordinal number, alpha, the successor of alpha is alpha union {alpha}. This means that for any number alpha, the successor for that number is alpha + 1."
For a finite ordinal number like 1, 2 or 3, the successor for that number is the number + 1. So the successor for 1 is 2, the successor for 2 is 3, and the successor for 3 is 4. Set theory contains other types of ordinals, called countably infinite ordinals, like w, w + 1, and w + 2. The successor for w would be w + 1, and the successor for w + 1 would be w + 2.
A maths processor is a term used in computer science to describe any computer. The computer is basically a number processor that processes binary code (0s and 1s) in the central processing unit (CPU).
A maths processor can be any device or program that handles computer code. For example, a mainframe computer is a maths processor, as is a handheld graphing calculator. Maths processors can also be used to refer to specific pieces of software that crunch numbers and draw graphs.
