This word refers to the ability to think correctly and reasonably, including observation, comparison, analysis, synthesis, abstraction, generalization, judgment and reasoning.

It is also called "abstract thinking" to reflect the essence and laws of things with thinking forms such as concept, judgment and reasoning. Logical thinking follows formal logic rules, such as unity, law of contradiction, law of excluded middle and law of sufficient reason.

Logical thinking is divided into perceptual and rational, and the latter uses clear thinking direction for in-depth analysis. It is also the key ability to learn mathematics and other subjects well and deal with daily problems, which is very important for personal development.
