Generally after writing some equations in the equation environment you explain the different letters in it in some text after.



I generally put those letter in $x$ to obtain the same formatting as in the equation. But at the same time is also just italic, so maybe textitx would be better?



Thanks and have a nice day.

    Try $v$ and textitv to see that the output in an article with default LaTeX font will be different. In beamer font will be the same ... but what if you need a $x_1$ somewhere... Then you have to use both ways and this is not the best idea?

You should use $x$ when writing about a mathematical variable for two main reasons:



  • it will be typeset in your math font (it's not just italic, but also a general font switch) which will make it consistent with all other math in your document

  • it is better logical markup (you want to talk about math so your markup reflects that it is math).

Furthermore, one could argue that you should, in general, avoid text styling commands like textit and rather use own commands for logical markup but that depends on your preference and the document, so the two reasons above are much more important.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
