You can list them out and add them up: 3 + 13 + ... + 193 {20 items}, or you can recognize the sequence: (n = 0..19) of (n*10 + 3), the sum would be 20*3 + 10*Sum[(n=0..19) of just n], which is 20*3 + 10*[190] = 60 + 1900 = 1960. If you add up the column of numbers, you get the same result.
When the quotient of two integers is positive, either both integers are positive or both negative. When the quotient of two integers is negative, one of the integers is positive and one negative. When the quotient of two integers is zero, the first integer is zero and the second one is anything but zero.
