Does short term gain attracts surcharge tax of 10%

1) Does short term gain attracts surcharge tax of 10% apart from eduction cess of 3% ?

2) is the short term gain tax of 10% is to be added to the net taxable income from salary & other sources like interest and then  need to calculate the surchage and eduction cess tax ? or surcharge and educess need to calculated separately for ST gains ?

Thanks

Josh
