the case statement understands shell patterns , not number ranges. rewrite program follows:

#!/bin/bash  echo -e "what annual income? " read annual_income  if (($annual_income == 0))      echo "you have no taxable income." elif ((24100 <= $annual_income && $annual_income <= 42199))     echo "with annual income of $annual_income, in lowest income tax bracket total effective federal tax rate of 1.5%." elif ((42200 <= $annual_income && $annual_income <= 65399))      echo "with annual income of $annual_income, in second income tax bracket total effective federal tax rate of 7.2%." elif ((65400 <= $annual_income && $annual_income <= 95499))     echo "with annual income of $annual_income, in middle income tax bracket total effective federal tax rate of 11.5%." elif ((95500 <= $annual_income && $annual_income <= 239099))      echo "with annual income of $annual_income, in fourth income tax bracket total effective federal tax rate of 15.6%." elif ((239100 <= $annual_income && $annual_income <= 1434900))       echo "with annual income of $annual_income, in highest income tax bracket total effective federal tax rate of 24%." fi
