mathematics is to use the “tombstone” in place of “QED”. This “tombstone” notation is attributed to the great mathematician Paul R. Halmos (1916– 2006). Some Notation from Set Theory ⊂ (the is included in sign) means “this set is a subset of” and ⊃ (the includes sign) means “this set has as a subset”.

Notes on Notation Dylan Zwick Summer, 2009 These notes address some common forms of mathematical notation that you’re likely to see in this and future math classes, but you may not have seen before. I won’t guarantee that these notes are exhaustive or free from typos, but I hope they help. 1 Set Theory The basic object in mathematics is a set.

Intro to Mathematical Notation Emma McKay September 2017 Version 1.0 1 Introduction This document summarizes much of the notation used in Math 137. Developing familiarity with these symbols is like developing vocabulary and grammar in the language of mathematics; these symbols aren’t just shorthand for English.
