Origins and meanings of mathematical and scientific symbols, from the magnificient to the obscure. Equal sign. Double-harpoon. Integration sign. Infinity symbol.
On the one hand we have the rules for working with strings of symbols – rules such as modus ponens above; on the other hand we are looking at meanings. This latter is the study of semantics. The former is syntax – the study of the way that language is put together from symbols. ...

1.1 Logic Symbols and Truth Tables explain their meanings and give their English versions,while also pointing out where casual English interpretations often di(er) from each other as well as their formal meanings. It is useful to learn to read the symbols above as they would usually be said ...
Mathematical propertiesBased on data from a series of teaching experiments on standard tools of mathematical logic, this paper characterizes a range of student meanings for mathematical properties and logical connectives. Sdoi:10.1007/s40753-017-0055-4Dawkins...
Based on this understanding of a need for greater preciseness, Frege presented Begriffsschrift [Frege, 1879], the first formalisation of logic giving logical concepts via symbols rather than natural language. “Begriffsschrift” is the name both of the book and of the formal system the book pre...
Intuitive and visual thinking: use intuitive and visual ways to understand mathematical concepts and processes, such as revealing the essence of mathematical concepts through graphics, examples or physical meanings. Semantic connection: Explore the internal connection and logical structure among mathematical ...
Let Σr be a signature with 0, 1 as constants and function symbols for addition x+y, opposite −x, and multiplication x⋅y. Σr is the signature of both rings and fields. We add a function symbol ÷ for division, with the design decision that x÷y is intentionally partial. This ...
The Basics If you have ever learned or tried to learn a new language, you know that you always start with the basics. Let's look at some basic math words and symbols and define what they mean. Level 1 Unit 2 Lesson Summary Register to view this lesson Are you a student or a ...
Once the compilation process has successfully completed, the caller can then obtain a list of symbols and their associated types from the DEC. The kinds of questions one can ask regarding the dependent entities within an expression are as follows: * What user defined variables, vectors or ...
