Is this condition necessary, sufficient or neither?

A necessary condition must be present, while a sufficient condition is enough to produce the result under the stated rules. Scoring at least 40 is necessary for a course that also requires attendance. The score alone is not sufficient if a student can still fail because the attendance requirement is unmet.

explanation

Explain why each step works

A worked solution can show what to do without revealing why the steps are valid. Adding a short reason beside each important step turns the sequence into an explanation. In an equation, subtracting the same amount from both sides preserves equality; naming that reason makes the action understandable.

assumptions

Which assumption is carrying your conclusion?

Every plan relies on something being true. A weekend event might assume that guests are free, the venue is accessible and the equipment works. Listing these assumptions exposes where the plan is fragile. The most important assumption is often the one that would change the decision if it proved false.
