Deduce logical rule[1]
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
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
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].
