title: Batch file basics: Adding a hardcoded integer to a variable in a for loop
body: <p>I want to simply add 10 to the variable "%%i" in this batch file code and print it out to the screen. numbers.txt is a file that contains a single column of numbers.</p>
  
  <pre><code>FOR /F %%i IN (numbers.txt) DO (
      set /a "T=%%i+10"
      @echo %T%
  )
  </code></pre>
  
  <p>For example, if %%i was 1 I would want T to be 11.</p>
  
  <p>Thanks.</p>
