TITLE: What is the difference between Modulus, Absolute value and Modulo?
QUESTION [15 upvotes]: When referring to the absolute value I have said Modulus. People then correct me and say that that is the operation where you find the remainder. Then I get confused because I've seen people say modulo for the remainder operation. Also if my first statement is correct why do we have two words for absolute value?

REPLY [2 votes]: We should keep the distinction between modulus for absolute value and modulo for modular arithmetic. Most of the literature do not keep this distinction.
