What is math mode ? For many people the most useful part of LaTeX is the ability to typeset complex mathematical formulas. for the sake of simplicity, LaTeX separates the tasks of typesetting mathematics and typesetting normal text. This is achieved by the use of two operating modes , paragraph and math mode .

Math Mode LATEX has a special mode for formatting mathematical formulas. In addition to displaying complicated mathematical notations, this mode allows the use of: • Subscripts and superscripts • Greek letters and various special symbols Thus, math mode is also useful for some nonmathematical text: The CH3COOH was irradiated with α-rays ...
These mathematical typography issues are an interplay of typesetting algorithms built into TeX engines together with certain spacing parameters contained in math fonts. Those font parameters help fine-tune math typesetting according to the design characteristics of the math font (s) being used. Overriding default mathematical styles
Typing inside \begin {math}...\end { math } in LaTeX Several math environments in LaTeX enter the math mode automatically, such as equation, align, alignedat, gather etc. Several characters/symbols being connected to math content require entering the math mode , such as \mathbb {R} etc. Share Improve this answer edited Jan 13, 2019 at 7:44
Typesetting complex mathematics is one of the greatest strengths of LaTeX . You can mark up mathematics in a logical way in what is known as 'math mode' . Math mode In math mode , spaces are ignored and the correct spacing between characters is (almost always) applied. There are two forms of math mode : inline display
The mathematics mode in LaTeX is very flexible and powerful, there is much more that can be done with it: Subscripts and superscripts Brackets and Parentheses Fractions and Binomials Aligning Equations Operators Spacing in math mode Integrals, sums and limits Display style in math mode List of Greek letters and math symbols Mathematical fonts
Spacing around operators and relations in math mode are governed by specific skip widths: \thinmuskip (by default it is equal to 3 mu) \medmuskip (by default it is equal to 4 mu) \thickmuskip (by default it is equal to 5 mu) \begin{ align* } 3ax+4by=5cz \\ 3ax<4by+5cz \end{ align* } Open this example in Overleaf
In LaTeX math mode , spaces are overlooked, and letters are rendered in italics. Hence, in order to add normal text, we need special commands such as \text, \textrm, \mbx and \textnormal. This post discusses these methods and highlight the difference through illustrative examples.
In a math environment, LaTeX ignores the spaces you type and puts in the spacing that it thinks is best. LaTeX formats mathematics the way it's done in mathematics texts. If you want different spacing, LaTeX provides the following four commands for use in math mode : \; - a thick space. \: - a medium space. \, - a thin space.

Inline maths elements can be set with a different style: $ f ( x ) = \displaystyle \frac { 1 }{ 1 + x} $ . The same is true for display math material:

\begin { eqnarray* }
f(x) = \sum _{ i=0 }^{ n } \frac { a _ i }{ 1+x } \\
\textstyle f(x) = \sum _{ i=0 }^{ n } \frac { a _ i }{ 1+x } \\

This article explains how to manually adjust the style of typeset mathematics—but we’ll start with a quick reminder of the visible differences between inline and display style math.

Typeset mathematics contained inline (within) with the text of a paragraph needs to take less space than the same math typeset outside the paragraph text as standalone, display-style, material. To see this in practice, let’s explain that the equation f ( x ) = ∑ n i = 0 a i 1 + x may diverge or converge depending on the value of x . We can also typeset f ( x ) outside the paragraph in display style:

Even a cursory glance at the previous example reveals changes in the size and formatting of math symbols, such as ∑ and the placement of its limits, together with variations in size/positioning of superscripts, subscripts and fractions.

These mathematical typography issues are an interplay of typesetting algorithms built into TeX engines together with certain spacing parameters contained in math fonts. Those font parameters help fine-tune math typesetting according to the design characteristics of the math font(s) being used.

Occasionally you may want to change the default style used to typeset a piece of mathematics. For example, you might want to change inline math, such as f ( x ) = 1 1 + x , and include it in the paragraph but typeset in display style: f ( x ) = 1 1 + x , although it does impact heavily on the line spacing.

TeX engines provide several commands which can be used to override the default style in which a piece of math is typeset:

The canonical example is taken from page 142 of the TeXBook, although we've replaced $$ by LaTeX's preferred \[ and \] :

The default typesetting style can be amended by using the \displaystyle command:

Here’s another example which demonstrates the effect of \textstyle , \scriptstyle and \scriptscriptstyle :
