There are three meanings of calculation: first, according to the known number, the unknown number is obtained through mathematical operation; The second is to consider; Planning; The third is the meaning of calculation, secretly plotting to kill people.

Calculation means four: one is to calculate the quantity; The second is to consider and plan; The third is speculation and estimation; The fourth is to secretly plan harm. By looking up the dictionary, I didn't see much difference between calculation and calculation, but I found a new meaning of calculation, "planning harms people."
