Need help getting totals. does nvl(' ',0) return a numeric 0 ?

Question

I am having problems trying to total some columns and I think it has to do with the sql not seeing the information as numeric.
I created this to test. With this nvl it displays ORA-01722: invalid number
select bcount.b1,bcount.b2,bcount.b3,acount.a1,acount.a2,acount.a3,bcount.b1 + bcount.b2 + bcount.b3 + acount.a1 + acount.a2 + acount.a3 mytot
from
(select 10 item,nvl(' ',0) b1,2 b2, 3 b3 from dual) bcount,
(select 10 item,1 a1,2 a2, 3 a3 from dual) acount
where bcount.item = acount.item
Actual sql
select emp.file_no,nvl(reg.regcount,0) regcount,nvl(ded.dedcount,0) dedcount,rehrg.rehrgcount,rop.ropcount,vs.vscount,
wtc.wtccount,timeline.tlcount,hl.hlcount,addl.addcount,op.opcount,oi.oicount,opoi.opoicount,
regcount + dedcount mtotal
if regcount = 8 and dedcount = 0 I get blank for my mtotal.
I think its because the nvl returns a 0 but the sql does not know this to be a number.
What do I do?
