### sense in the lessons

In maths, logic puzzles ask pupils to use clues to work out who has which pet or what number is hidden; good answers explain each step. In coding, «if … then … else» and «and / or / not» are logic. In everyday life and stories, someone with logic is calm and reasons well; something «against all logic» is surprising or silly. Phrases: «logic puzzle», «use your logic», «the logic behind», «there's no logic in it», «flawed logic».

### note

Uncountable: «good logic», not «a logic» in everyday speech. Adjective: logical; opposite: illogical. A logical argument can still reach a wrong answer if one starting fact is false. In maths problems, logic means showing each step that leads to the answer.
