Numbers no not have a character component. They are just numbers. But you can always call East a POSITIVE direction. West is therefore a NEGATIVE direction. So apply a sign to the numbers, depending on your "direction" flag. Then you can just add the results.
Effectively, I am telling you to NOT have separate character flag. Make the sign of the number indicate the direction. So here, we wuld have
x = 50;
z = -3;
Now the composite result is trivial.
xplusz = x + z
xplusz = 47
And the net result is positive, so it is an easterly direction.
