What is your algorithm for determining if a number is prime? Not the definition, a list of steps to determine it.

yes, it is a requirement. the way i will find out if a number has a remainder is to multiply by two times the divisor and subtract that from the number.

Try debugging your code by printing out each number it tests and show whether that number is prime or not.

in order to find out if the number is prime using integers i am subtracting the quotient*divisor from the dividend. if the result is >0 in every instance i am trying to make the program understand that the number is prime and to add it to the sum. if the result of dividendquotient*divisor is 0 then i want the program to skip that number and not add it to the sum.
