Social Sciences
Seishun Bunko / "First Establish the Basics" is the royal road of learning something. Therefore, in this book, I will review "everything I learned in elementary school," which is supposed to be the foundation of the basics. In order to review the important items in "Social studies," "Science," "Japanese," and "Mathematics," I have summarized the points so that I can review the important items in "Social studies," "Science," "Japanese," and "Mathematics" in the shortest period of time. In other words, I think I can hear people say, "The things I learned in elementary school are all right." Is that true? For example, Mathematics. Why is the sum of the internal angles of a triangle 180 degrees? Or, Science. Can you proudly explain why the moon is full or short? Originally, "learning in elementary school" should be "common sense" for adults. If you feel even a little anxious about "Is it okay?", please check the current "academic ability" = "common sense ability" in this book and thoroughly review it.
