Raster Calculator: multiple equations based on multiple rasters in one run

I have recently changed ArcGIS 9.3 to ArcGIS 10.
In the 9.3 it was possibly to enter multiple conditions based on multiple rasters, as well as to enter multiple equations in one run of the tool - so I could with one operation perform e.g.:

tra = Con(([depth] > 13.44 & [DO_sum_mean10] > 6.795 & [DO_win_min10] > 6.81 & [mud] > 0.87), 9, 0)
expo = Con(([depth] > 13.44 & [DO_sum_mean10] > 6.795 & [DO_win_min10] > 6.81 & [mud] < 0.87), 5, 0)
epid = Con(([depth] > 13.44 & [DO_sum_mean10] > 6.795 & [DO_win_min10] < 6.81 & [sal] > 18.58), 4, 0)
epi = Con(([depth] > 13.44 & [DO_sum_mean10] > 6.795 & [DO_win_min10] < 6.81 & [sal] < 18.58), 3, 0)
deep = Con(([depth] > 13.44 & [DO_sum_mean10] < 6.795), 1, 0)
epi2 = Con(([depth] < 13.44 & [maxbed10] > 29.935 & [veg_comv311] == 0 & [veg_comv32] == 0), 3, 0)

In ArcGIS10 this is not the case any more - there is only an option of one output raster at a time in raster calculator (it Builds and executes a single Map Algebra expression).
So my question is what could be the way to quickly execute the set of expressions above in ArcGIS10? Should that be the Python? I have thought of it but since I am not very familiar with it I have not managed to find the way to fully incorporate my expressions into Python.
I would really appreciate any advises and ideas. Thank you in advance!
