I don't want to read the number string from both left to right and Ruth to left. So, I

iterate through each row and read the number string from left to right
Store each number along with its cell range. ie: 467 is 0-2.
Then from each symbol, find out if the position of the symbol +/-1 falls into any range. If so then sum that number.
