Using Numbers as a timecard

My boss just switched my desktop to an iMac running os High Sierra version 10.13.3 & I'm responsible for making my own time sheets. I have been using Microsoft excel for years and I tried using the same cell formulas to calculate my hours and total pay but it's not working.

I have the basic Log In, Out Lunch, In Lunch, Log Out, Total Hours, Total Pay but I don't know what formula to use to calculate the Total hours cell.

I have figured out the formula for Total Pay already, which also is a different formula than excel. I love working on this new iMac but I'm a little frustrated trying to create my timesheet.
