Description
Book Introduction
"Lightsen," a problem-solving book that makes math easier

"Lightsen" is a basic textbook that reduces the burden of learning by adjusting the amount and difficulty so that even students who struggle with math can study the types of problems without burden.
The A and B stages are focused learning systems that exclude advanced types. Stage A reinforces basic problems to ensure sufficient learning and confirmation of concepts, while Stage B systematically subdivides types based on concepts and solution methods required for problem solving, focusing on essential types, to enable three-dimensional learning by difficulty level and type.
With 『Lightsen』, you can solidify your skills and build confidence in math.
