The concept and method of calculus reform are put forward. The calculus function is defined as a set of infinite multiplications that are not repeatedly combined and synchronized with the order value and term order. Central to the proposed calculus reform is the mathematical combination (group) process. Prove its characteristics of equivalence, symmetry and asymmetry, unit (quantum), isomorphic consistency, normalization, parallel / serial computing. The logarithm is established based on the characteristic pattern of real infinity (the average of the positive, neutral, and inverse functions), which is called the circular logarithm. Obtain the unity of open and closed, discrete and entangled, probability and topology, sphere and ring, and map to the logarithmic equation calculation of circle in closed [0 to 1] infinite arithmetic. For mathematical relativity.
