There is a big difference. Algebra is about the calculation of numbers: exactly, it is about the calculation of real numbers and complex numbers, while geometry is about the reasoning of figures: geometry is a subject that studies the structure and properties of space. Algebra mainly examines your computing ability, while geometry mainly examines your reasoning ability and spatial imagination ability. Question: Is there anything else besides algebra and geometry in high school mathematics? Answer: Senior high school mathematics doesn't learn anything except algebra and geometry, which my math teacher added: Is the correlation operation between series an algebraic problem? Answer: Yes, algebra mainly solves the operation of numbers and the relationship between numbers; Geometry is the study of the properties of plane and three-dimensional figures. With the help of algebra, the application of space vector is. Question: What kind of function does it belong to? Is it algebra? A: All function classes belong to algebra.
