Many line by line calculations

Question

Hi All,
I have a component with couple methods, each method is the result of query from the database.
I want to do some calculations after i get the data from the server. I am lokking for a solution with good performance because I have many calculations to do.
Code:
<cfset myObj = CreateObject("component", "cfcs.myComponent") />
<cfset firstQry = myObj.getFirstResult(arguments.A, arguments.B) />
<cfset secondQry = myObj.getSecondResult(arguments.A, arguments.B) />
Both query results have the same structure myID, myDesc, year_1, year2, year3
firstQry have 10 rows, how can I sum the years row 3 (myID = 3) and years row 5 (myID = 5) ?
and add the result of the calculation into firstQry as line 11 (new myID = 11).
secondQry have one row result.
How can I multiple the firstQry years row 4 (myID=4) with the secondQry years row 1 (only row myID = 1)? 
and add the result into firstQry as line 12 (new myId =12).
I was thinking to use query of query but I wondering if it is a better way to do this.
Thanks in advance for your help.
Best,

Q of Q have many limitations. I have to generate a lot of code.
If I want to do the first calculation, i have to create another query because I cannot use query table alias like:
<cfquery dbtype="query" name="firstQry2">
select * from firstQry
</cfquery>
<cfquery dbtype="query" name="qryResult">
select 11 as myID, 'cal 12' as myDesc
<cfloop from="1" to="3" index="y">
,(firstQry.year_#y# + firstQry2.year_#y#) as year_#y#
</cfloop>
from firstQry, firstQry2
where firstQry.myID = 3
and firstQry2.myID = 5
</cfquery>
Is this correct, or I can do this in a better way?
Now, how can i insert the result into firstQuery?
I try to do another Q of Q with insert but I am getting an error.
Query Of Queries syntax error.
  Encountered "insert. 
<cfquery dbtype="query" name="insertQry">
insert into firstQuery (myID, myDesc
<cfloop from="1" to="3" index="y">
,year_#y#
</cfloop>
select  myID, myDesc
<cfloop from="1" to="3" index="y">
,year_#y#
</cfloop>
from qryResult
</cfquery>
