How to substract my s_sum column in sql statement ?

S_MONTH S_SUM
--------------- ----------

JAN                   1000
FEB                   1200
MAR                   1250

I want the result should look like this :

S_MONTH S_SUM
--------------- ----------

JAN                   0
FEB                   200
MAR                   50

Any idea please?

Thanks,
Jonny
