We use a combination of the test-curve method of Porteous, and the localization methods in equivariant cohomology. Our formulas are independent of the codimension, and they are computationally efficient for d less than 7.Latex, 70 pages, details added and misprints correctedAlgebraic TopologyCommutative Algebratext
