These are basically placed on the centre of the page and the equations are important ones that deserve to be highlighted. There is one symbol that can be automatically superscripted that is, '. Multi-line equation numbering would also be somewhat challenging outside KaTeX. Binomial coefficients are written with command \binom by putting the expression between curly brackets. -4 + 5x &= 2+y \nonumber \\ 3. To get an auto-numbered equa-tion, use the equation environment; to assign a label for cross-referencing, use the \label The command \sqrt produces the square root. Following is the step by step tutorial of how to insert auto-numbering to the equations. 2. If you use NexT theme, see here on how to enable MathJax. The aim is to create a template that can be used to automatically generate the table and equation with equation number to the right. For example, $a + b$, $a - b$, $-a$, $a / b$, $a b$. We use the equation environment to wrap our equation or we can use equation if we want it to be numbered. The equation number produced by {{ EquationNote }} is a link that the user can click to go immediately to the cited equation. To overcome these challenges, you can use the "asmmath" package. In LaTeX, by default, tables are numbered Table 1, Table 2, Table 3 an so on (or Table 1.1, Table 1.2, Table 2.1, etc if you’re using chapters).
