HANDBOOK FOR SPOKEN MATHEMATICS | LAWRENCE CHANG

This handbook answers some of the needs of those who have to deal with spoken Mathematics , yet have insufficient background to know the correct verbal expression for the written symbolic one .

Mathematical material is primarily presented visually , and when this material is presented orally , it can be ambiguous .

While the parsing of a written expression is clear and well-defined , when it is spoken this clarity may disappear .

For example , " One plus two over three plus 4 " can represent the following four numbers , depending on the parsing of the expression : 3/7 , 1 2/7 , 5 , 5 2/3 . However , when the corresponding written expression is seen , there is little doubt which of the four numbers it represents .

When reading Mathematics orally , such problems are frequently encountered .

Of course , the written expression may always be read symbol by symbol , but if the expression is long or there are a cluster of expressions , it can be very tedious and hard to understand . Thus , whenever possible, one wishes to have the written expression spoken in a way that is interest retaining and easy to understand .

In an attempt to alleviate problems such as these , this handbook has been compiled to establish some consistent and well-defined ways of uttering Mathematical expressions so that listeners will receive clear , unambiguous , and well-pronounced representations of the subject .

PROJECT MATH ACCESS | HANDBOOK FOR SPOKEN MATHEMATICS

The content of this portion of the site was adapted from Lawrence Chang's Handbook For Spoken Mathematics : Larry's Speakeasy .

All sections of the original work are included except the section entitled , Diagrams and Graphs . That chapter contains extraordinarily complex graphics which would be impossible to display in such a fashion that it would be accessible to those who are blind or severely visually impaired .

The focus of Chang's work is to provide the wherewithal by which sighted individuals can read Mathematics to persons who are blind .

Chang describes in words each symbol in the major branches of Mathematics , from the simplest to the most complex .

In essence , Chang's work represents the spoken vocabulary of Mathematics .

Thus , one use to which this work can be put is to assist persons who are blind in training sighted readers to accurately read Mathematics .

We have added to the reservoir of information in several ways .

LIST OF MATHEMATICAL SYMBOLS | WIKIPEDIA

This is a list of symbols found within all branches of Mathematics to express a formula or to represent a constant .

When reading the list , it is important to recognize that a Mathematical concept is independent of the symbol chosen to represent it .

For many of the symbols below , the symbol is usually synonymous with the corresponding concept ( ultimately an arbitrary choice made as a result of the cumulative history of Mathematics ) , but in some situations a different convention may be used .

For example , depending on context , the triple bar " ≡ " may represent congruence or a definition .

Further , in Mathematical logic , numerical equality is sometimes represented by " ≡ " instead of " = " , with the latter representing equality of well-formed formulas .

In short , convention dictates the meaning .

Each symbol is shown both in HTML , whose display depends on the browser's access to an appropriate font installed on the particular device , and in TeX , as an image .

LIST OF MATHEMATICAL SYMBOLS BY SUBJECT | WIKIPEDIA

This list of Mathematical symbols by subject shows a selection of the most common symbols that are used in modern Mathematical notation within formulas , grouped by Mathematical topic .

As it is virtually impossible to list all the symbols ever used in Mathematics , only those symbols which occur often in Mathematics or Mathematics education are included . The following list is largely limited to non-alphanumeric characters .

It is divided by areas of Mathematics and grouped within subregions .

Some symbols have a different meaning depending on the context and appear accordingly several times in the list .
