If statment in Excel

Hy! Could someone help me out with this equation ? I looked onlyne for some solution but nothing could work :/

I am trying to figure it out how to calculate the following:

if anexe ( temporary higher work hours ) is greater then the contract hours, are equal to anex - worker hours( which i called uren ) I want so calculate a if statement more or less like this:

If Anexe > contract, is equal to Anex - uren

else Anexe < contract then contract - uren

Thank you for helping out already!
