First, the meaning is different: operation generally refers to the operation of formulas and functions, while calculation generally refers to numbers. Operation refers to what laws are used for operation, such as addition, subtraction, multiplication and division. And the calculation lies in a process, logarithmic analysis and solution. The difference is that operation is a noun and calculation is a verb.
Second, calculation refers to the process of calculating the unknown quantity according to the known quantity; Operation refers to the process of calculation according to mathematical laws. Those laws are the most basic and simple things, and there are axioms. Operations can derive known and unknown formulas, which can simplify the calculation process. Calculation, all math tests, big and small, are calculation processes.
The relationship between data and data
When the data are in a calculation formula, it is said that there is a calculation relationship between the data. Some calculation relationships are determined by the intrinsic properties of data (such as coefficient matrix, specific items in series and items in formulas) and physical location (display or representation of data in an image, relationship of curves in rectangular coordinate system, cpu array and storage of data). In mathematical formulas, data and operators have specific and detailed relationships, such as data number, left and right functions, formula form and so on.
