title: adding variables numical values (newb question)
body: <p>Yesterday i had a look at how to set values of variables from nummbers stored in external txt files</p>
  
  <p>the variables then needed to be added up so i used trial and  error first</p>
  
  <p>((XVAL) + (NEWVAL))</p>
  
  <p>assuming that XVAL was set to 10 and NEWVAL was set to 20 i expected to get the answer of thirty but waqs presented with the new value of 10 20</p>
  
  <p>VB.net pysicaly added the two values together but i wanted the mathematical product of the two which is ((10) + (20)) = 30</p>
  
  <p>yep its a newb question could anyone explain how to achieve what im affter</p>
