Code Latex Sum

In summary, Latex Code for Upper Sum refers to the coding used in LaTeX to represent the mathematical concept of an upper sum, which is used in calculus to approximate the area under a curve. The upper sum is typically represented in LaTeX using the command \overline{S}, and an example of this code would be \overline{S} = \sum_{i=1}^{n} M_i \Delta x_i. There are no variations in the code for representing an upper sum across different versions of LaTeX, although there may be slight differences in syntax for related commands or functions. To use Latex Code for Upper Sum in a document, you will need to have a LaTeX editor or compiler installed and then input the code into

Is this what you want?
\sum_{j \in J} --> $\displaystyle \sum_{j \in J}$

and
\underset{x \in B_j} {sup} -->$\displaystyle \underset{x \in B_j} {sup}$

Alternatively, \sup_{x\in B_j} --> $\displaystyle \sup_{x\in B_j}$. (The symbol for sup then appears in Roman type rather than italics.)
