In German, the reading of mathematical operations and mathematical symbols often annoys many students who want to study in Germany. Because these symbols can't be found in dictionaries, they can only be summarized from German textbooks by studying in Germany for a period of time. Here I share a summary of my own operating symbols with his family. Some symbols can't be typed, so they can only be replaced by pictures. Welcome to add
