# logic

noun (logic; uncountable)

«logic» in the English dictionary: everyday and in Jewish tradition — its meanings, how the lessons use it, and examples, each with its tree on Mova.

2. Logic is also the study of correct reasoning, a part of maths and philosophy. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/L/logic/#m2)
3. The logic of something is the reason or sense behind it: «I don't see the logic of that plan». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/L/logic/#m3)
4. (computers) Logic is the set of rules and true/false steps a computer or program follows. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/L/logic/#m4)

### 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.
