N % 5 == 0

Can someone explain to me how this formula can determine the variables can multiple to 5? Thanks

U know in mathematics how we finding multiple check all multiple of 5 it will completely divisible by 5 means if u divide any number which us divisible by 5 completely it will give remainder zero . And here

N%5 = Remainder

Answer 3

Here use of Modulous Operatior which gives the result remainder, and if any number is divided by a number and it gives remainder zero means it is divisible by that number
