We decompose a real-world situation and look for logical rules which may govern a situation. The main idea here is to break the situation into smaller parts and then look for logical rules which we can model with a computer. This topic is very closely related to abstraction and you very much need to understand boolean operators
Logical rule[edit]
In the context of a high school introduction to computer science course, a logical rule is a rule which has at least one of the following:
- IF
- AND
- OR
- NOT
- NAND
- NOR
- XOR
When deducing logical rules, you should simplify and reduce the situation into small parts decomposition.
Logical reasoning determines if algorithms will work by predicting what happens when the algorithm’s steps - and the rules they consist of - are followed[2].
Do you understand this?[edit]
