In the linguistic field of pragmatics, an inference is said to be defeasible or cancellable if it can be made to disappear by the addition of another statement, or an appropriate context. For example, sentence [i] would normally implicate [ii] by scalar implicature: i: Alice has three children.ii: Alice has exactly three children. But the implicature can be cancelled by the modification in [ib]: ib: Alice has three children, and possibly more. Whereas conversational implicatures and presuppositions may be cancelled, an entailment may not be. For example, [i] entails the proposition "Alice has at least three children", and this cannot be cancelled with a modification like: ic: Alice has three children, and possibly less. (Wikipedia).
Inferences: Implicature - Semantics in Linguistics
In this video on #semantics/#pragmatics in #linguistics, we talk about our second type of inference: implicature, and do a few examples with the defeasability / cancellation test and the reinforcement test. Join this channel to get access to perks: https://www.youtube.com/channel/UCGYSfZb

Theory of numbers: Multiplicative functions
This lecture is part of an online undergraduate course on the theory of numbers. Multiplicative functions are functions such that f(mn)=f(m)f(n) whenever m and n are coprime. We discuss some examples, such as the number of divisors, the sum of the divisors, and Euler's totient function.

Solving and graphing a linear inequality word problem
Learn how to solve multi-step linear inequalities having no parenthesis. An inequality is a statement in which one value is not equal to the other value. An inequality is linear when the highest exponent in its variable(s) is 1. (i.e. there is no exponent in its variable(s)). A multi-step
