3 if statements in One cell

HI I am trying to combine 3 if statements in one but the order keeps coming out wrong.

The three statements separately are

If (B10>A1,0)

If(B10=A1,-B9)

If(B10<A1, B9+b8)

Can anyone help put these into one statement.

Thanks

Try

=IF(B10>A1,0,IF(B10=A1,-B9,B9+B8))

great thanks!!

You're welcome
