Ok so just a few code tidbits needed - a function to add all the odd integers from 1 to n, a function that adds all the integers up from 1 to a number equalling that number such as 1 + 2 + 3 + 4 if they enter 10, and a function that adds the digits of a negative number such as 3 if the number is -12 or 5 if the number is -23.

Thanks please
