A book for abstract algebra with high school level
Any book that I find on abstract algebra is somehow advanced and not OK for self-learning. I am high-school student with high-school math knowledge. Please someone tell me a book can be fine on abstract algebra? Thanks a lot.
Three books I know of that really are high school level are listed below. Although the books thus far listed (Gallian, Herstein, Fraleigh, Pinter, etc.) are fine texts, these are standard upper undergraduate college level textbooks, not books specifically written for good (but not necessarily near genius level) high school students.
Irving Adler, Groups in the New Mathematics. An Elementary Introduction to Mathematical Groups Through Familiar Examples, The John Day Company, 1967, 274 pages.
Francis [Frank] James Budden, The Fascination of Groups, Cambridge University Press, 1972, xviii + 596 pages.
Israel Grossman and Wilhelm Magnus, Groups and Their Graphs, New Mathematical Library #4, Random House, 1964, viii + 195 pages.
Abstract algebra by John Fraleigh and JA Gallian Contemporary Abstract Algebra
I'm astonished that this wasn't mentioned:
This book is designed for prospective and practicing high school mathematics teachers, but it can serve as a text for standard abstract algebra courses as well. The presentation is organized historically: the Babylonians introduced Pythagorean triples to teach the Pythagorean theorem; these were classified by Diophantus, and eventually this led Fermat to conjecture his Last Theorem. The text shows how much of modern algebra arose in attempts to prove this; it also shows how other important themes in algebra arose from questions related to teaching. Indeed, modern algebra is a very useful tool for teachers, with deep connections to the actual content of high school mathematics, as well as to the mathematics teachers use in their profession that doesn't necessarily "end up on the blackboard."
The focus is on number theory, polynomials, and commutative rings. Group theory is introduced near the end of the text to explain why generalizations of the quadratic formula do not exist for polynomials of high degree, allowing the reader to appreciate the more general work of Galois and Abel on roots of polynomials. Results and proofs are motivated with specific examples whenever possible, so that abstractions emerge from concrete experience. Applications range from the theory of repeating decimals to the use of imaginary quadratic fields to construct problems with rational solutions. While such applications are integrated throughout, each chapter also contains a section giving explicit connections between the content of the chapter and high school teaching.

When I was in high school (60 years ago) I stumbled on W. W. Sawyer's A Concrete Approach to Abstract Algebra. Google found it free at https://archive.org/stream/AConcreteApproachToAbstractAlgebra/Sawyer-AConcreteApproachToAbstractAlgebra#page/n5/mode/2up - I've linked to the page that describes why it might be suitable for you.
I am also in high school and two books I've used and found very accessible are:
1) 'Visual Group Theory' by Nathan Carter (the diagrams and illustrations are excellent, a bit pricey though)
2) 'Book of Abstract Algebra' by Charles C. Pinter (the 'Dover books on Mathematics' series of mathematics books are all worth a look)
I can attach the contents if you want.
