Hi, regarding last question in lab of arethmetic operations(calculcating average).
the below script(copied from the answers in the var/assets folder) does not retrive the average,
can someone kindly asssit?
when i type: bob@caleston-lp10:~$ ./calculate-average.sh 1 2 5
nothing is returned.
num3=3 sum=(( num1 + num2 + num3 ))
average=$(echo “$sum / 3” | bc -l)
