Moving excel formula/expression to access

[bowldog]

I have 5 fields(First,Second,Third,Sum,Sum1). The Sum field is the sum of the first, second and third. In excel I am using the following formula/expression to calculate the Sum1 field =IF(E1<0,E1+10,E1+0 - and it brings back single digit.
e.g.
First=3, Second=5, Third=8, Sum=16, Sum=6
Can I do this in an Access query, if so how?

Thanks in advance for any help.
