Do you ADD fat Calories with regular calories burned here?

YUMMY45

When I add my cardio treadmill workout, My Fitness Pal calculates a much higher number of calories burned than my treadmill monitor does. Here's the thing though. My treadmill monitor breaks down Fat Calories and Regular Calories. So my question again is, Do I add both together and report it on my daily exercise chart? Thanx for any help I can get out here...
