Remainder, a mathematical term. In the division of integers, there are only two situations: divisible and non-divisible. The remainder cannot be generated in a time-sharing manner. The remainder operation a mod b = c(b is not 0) means that the remainder obtained by dividing the integer A by the integer B is c, such as 7÷3 = 2 1. More professional symbols can also be written as 7÷3 = 2 and 1/3, or 7 mod 3= 1.

The remainder refers to the undivided part of the dividend in integer division (taking positive numbers as an example here), and the value range of the remainder is an integer between 0 and divisor (excluding divisor). [1] For example, if 27 is divided by 6, the quotient is 4 and the remainder is 3.

If a number is divided by another number, if it is smaller than another number, the quotient is 0 and the remainder is itself. [1] For example, if 1 is divided by 2, the quotient is 0 and the remainder is1; When 2 is divided by 3, the quotient is 0 and the remainder is 2.
