Konstante vs Faktor
factor
'der Faktor' and 'die Konstante' can both occur in mathematics, science, or when describing a situation. A factor influences a result; it can change depending on the situation or have different levels of importance. A constant stays the same and does not change. Learners may confuse the words because a constant can also be a factor in a situation. The most important difference is: 'Faktor' asks about influence, while 'Konstante' asks about the value or circumstance that remains the same.
