In the English Language Users Guide on page 423 there are multiple typos or incorrect formattings. All the examples concerning differentiation require a font change: e.g., (bt)2 should read (bt)2 where the numeral 2 is superscript.

Also in the French version of the user’s guide, “hexagesimal” has been wrongly translated to “hexadécimal” or “hexadécimaux” in several places (pages 29, 31, 32, 699).
There seems to be same issue in at least the Spanish version.
On the unit menu of the prime set in french. I suggest to translate "unit of time" (item number 5 in the unit menu) as : Unité de "Temps"... Actually the word is "Heure"...
