Used like this, eN (much more often EN) is just a symbol for 10N 10 N It is used because scientific notation is convenient for large and small numbers and it avoids the need for superscripts Superscripts used to be much more difficult to produce than they are today, and even today they are not easy in (some) word processors 12 5e says allocate 12 spaces to the total output (including signs

- What is an integral number? - Mathematics Stack Exchange
In normal use, integral length would be equal to some integer, while unit length would be of length 1 1 (see "unit number" here) Presumably the author meant, "in the unit (with a different meaning!) we use to measure lengths, these lengths are integer-valued"
- What does versus mean in the context of a graph?
I would agree with the rule " [dependent] versus [independent] " The word "versus" can mean "compared with," and it more frequently makes sense to compare a dependent value with its associated independent value, because well, the independent variable doesn't really "care" about the existence of the dependent variable, but the converse relationship is by definition
