Code:

I would like to use addition to know the total sum of all these numbes. How would i do that?

You could use for example the language awk on a script bash.
Calculate sum and average of multiple lines - awk in bash

Hello phsythax,

Can you use this script.sh ?

Code:

#!/bin/bash
sum=0
while read line
do
sum=`expr $line + $sum`
done < $1
echo "Sum is $sum"

execute it this way

Code:

sh script.sh /path/to/file/where/numbers/are/stored

Cheers !!!

Code:

awk 'BEGIN{s=0}{s+=$1}END{print s}' file

try to put in some effort next time

Code:

awk '{s+=$0}END{print s}' file
echo $(tr "\n" "+" <file)0|bc

For completeness:

Open the file with a spreadsheet program and use the summation button.

or you can use xcalc, that's probably installed

Then write a macro and open the file with a command that both opens it and runs the macro

. Truly there are many ways of skinning requirements/solutions cats.
