If over the course of a week dave operates the forklift for 10 hours and tom operates the forlife for 22 hours how many total hours do they operate the forklift?

32 hours.

Dave operates for 10 hours, Tom operates for 22. In order to find out how many hours total they operated the forklift, you have to add the two numbers together. 
10 + 22 = 32, so 32 hours is the total number of hours the forklift was operated
