Results don't display negative numbers

I have an application that accepts a 24 bit number and does some simple mathematical operations (see attached).  If number 3(a probe) receives a number lower than the constant that is being subtracted from it, which should result in a negative number, number 6(probe) displays a much larger, positive integer.

I'm sure that I must be missing something simple somewhere.

I thank you for your help in advance.

Probe 3 (and the constant wired to it) are likely represented as an U32 (unsigned).  Unsigned numbers have a range starting from zero and cant go negative.  Change the representation to I32 instead.

Thank you very much. I didn't realize the difference between unsigned integer and integer.
