Calculating Totals With Data From Access

I have done a fair amount of coding but very little in the way of maths type stuff

<code>
While Not objRSC.EOF
Response.Write "<tr><td>"
Response.Write objRSc("Item_Quantity") & "</td><td>"
Response.Write objRSc("Stock_item") & "</td><td>"
Response.Write objRSc("Stock_description") & "</td><td>"
Response.Write objRSc("Item_Price") & "</td></tr>"
objRSc.MoveNext
Wend
</code>

What I now want to do is to add all the Item_Prices together, .
