String "0" should be outside $(...)
Code:
echo $(tr '\n' '+' < numbers )"0"  | bc

Code:
$(tr '\n' '+' < numbers )

will give output like this
For ex:
Code:
10.456+123.567+456.876+234.987+

To make above work ,add 0 to the above expression

hi,
I used the following command
echo $(tr '\n' '+' < numbers )"0" | bc
But now also it is giving the same error-"Parse error".
