SQL can perform arithmetic operations like addition, subtraction, division or modulus.
Modulus is the remainder of a division between two numbers. It is represented by the symbol %.
Modulus is sometimes also referred to as modulo.
Modulo is written as:
4 % 2
For example when dividing numbers say 10 and 3, results in a remainer of 1
While dividing numbers 7 and 4, results in a remainder of 3
