I am writing a list of physical formulas, so I create this MWE:

endtasks

section*Example 2

task textbfExample f. $formula$
task textbfExample g. $another textformula$
endtasks

enddocument

I have many more formulas, however I find it difficult to continue in this way for five reasons:

1. I do not know how to correctly express the disposition of the items (two columns? Three?);


2. There are times when two formulas, one on top of the other, are stuck together, and the visual aspect is bad;


3. At most each element has two columns: Description. $formula$. Write the text in bold for each item and $...$ are a waste of time;


4. I do not know how to continue the numbering automatically between each section (I could change the counter but it is another waste of time because if I add a formula in the middle of the others I must manually change the value);


5. There are some formulas that have no description, only $...$.

Does anyone know how to reduce the time spent writing each item homogeneously?

Feel free to change the tags.

Thanks!

My proposal is to create a new environment, with a tabular whose column definitions allow you to have bold descriptions and math formulae without code repetition.

For the numbering, I copied from How to enumerate the rows of a table.
