Now I've not tried this and it is years since I even tried; but - I didn't
know you could type an equation and get a result in a bash script line like
that. But if you can, then you have to change which form of quoting
character you use which differentiates between quoting the term literally
like you got or forcing it to evaluate first. Try single '', double "" or
grarve accents ``.

Subject: bash scripting problem
Hi,
I am learning to shell script. One of my tasks is to print the value of
two numbers been added together. But first that final value must be
assigned to a variable.
So I write:
#!/bin/bash
#Print the value of 2 numbers added
x=10
y=15
z=$x+$y
echo $z
exit 0
I get 10 +15 as the output.
I want to get 25.
What am I doing wrong?
