To highlight an equation, `\bbox`

can be used. E.g,

1 2 3 4 5 6 | $$ \bbox[yellow] { e^x=\lim_{n\to\infty} \left( 1+\frac{x}{n} \right)^n \qquad (1) } $$ |

- Use
`\begin{array}…\end{array}`

and`\left\{…\right.`

. For example, you get this:$$

\left\{

\begin{array}{c}

a_1x+b_1y+c_1z=d_1 \\

a_2x+b_2y+c_2z=d_2 \\

a_3x+b_3y+c_3z=d_3

\end{array}

\right.

$$

Use `\require{cancel}`

in the first formula in your post that requires cancelling; you need it only once per page. Then use:

$$\require{cancel}\begin{array}{rl}

\verb|y+\cancel{x}| & y+\cancel{x}\\

\verb|\cancel{y+x}| & \cancel{y+x}\\

\verb|y+\bcancel{x}| & y+\bcancel{x}\\

\verb|y+\xcancel{x}| & y+\xcancel{x}\\

\verb|y+\cancelto{0}{x}| & y+\cancelto{0}{x}\\

\verb+\frac{1\cancel9}{\cancel95} = \frac15+& \frac{1\cancel9}{\cancel95} = \frac15 \\

\end{array}

$$

These are issues that won’t affect the correctness of formulas, but might make them look significantly better or worse. Beginners should feel free to ignore this advice; someone else will correct it for them, or more likely nobody will care.

It is often easier to read tables formatted in MathJax rather than plain text or a fixed width font. Arrays and tables are created with the `array`

environment. Just after `\begin{array}`

the format of each column should be listed, use `c`

for a center aligned column, `r`

for right aligned, `l`

for left aligned and a `|`

for a vertical line. Just as with matrices, cells are separated with `& `

and rows are broken using `\\`

. A horizontal line spanning the array can be placed before the current line with `\hline`

.

In general, you have to search in long tables about a specific symbol you’re looking for, things like $\Psi$, $\delta$, $\zeta$, $\ge$, $\subseteq$ … And it turns out that this operation can be frustrating and time consuming, which can cause the buddy to abandon writing the complete $\LaTeX$ sentence in his answer, or in some cases, the complete answer itself.

Often people want a series of equations where the equals signs are aligned. To get this, use `\begin{align}…\end{align}`

. Each line should end with `\\`

, and should contain an ampersand at the point to align at, typically immediately before the equals sign.

For example,

Use

`$$\begin{matrix}…\end{matrix}$$`

In between the`\begin`

and`\end`

, put the matrix elements. End each matrix row with`\\`

, and separate matrix elements with`&`

. For example,1234567$$\begin{matrix}1 & x & x^2 \\1 & y & y^2 \\1 & z & z^2 \\\end{matrix}$$

To see how any formula was written in any question or answer, including this one, right-click on the expression it and choose “Show Math As > TeX Commands”. (When you do this, the ‘$’ will not display. Make sure you add these. See the next point.)

`MathJax`

allows you to include mathematics in your web pages, either using LaTeX, MathML, or AsciiMath notation, and the mathematics will be processed using JavaScript to produce HTML, SVG or MathML equations for viewing in any modern browser.

In this article, we are going to talk about how to add `Mathjax`

on WordPress. As a result, you can write beautiful math formula on WordPress as in LaTeX.
