How to compare the size of scalar and vector

According to the basic definition, vector and scalar are defined according to the operation rules they follow. Vector: all physical quantities that follow parallelogram rules are called vectors; scalar: all physics that follow algebraic rules are called scalars. So what you have learned in Mechanics: displacement, velocity, acceleration, force, impulse, momentum, etc
