... operate on two operands. You know that.

• We are dealing with number representaion in a given base, hence the function should return a string, not an integer.
• What if the input is 64 instead of 8?

int octalSum=octal5+octal12;
Console.WriteLine(octalSum); // prints "19" i.e. uses invalid characters in the octal world.

int five=ReadAnOctalNumberFromConsole();  // let's assume you enter 5
int twelve=12;
int sum=five+twelve;
WriteToConsoleUsingOctal(sum); // prints "21"

string five="5";
string twelve="12";
string sum=OctalStringArithmetic.Add(five, twelve);
Console.WriteLine(sum); // prints "21" if you did it well
