Question

Create an add function should add two values sent to it. subtract function. A subtract function should subtract a received value from the value of 20. multiply function. A multiplication function should multiply the result from the add function times the result from the subtract function. A division function should divide the result from the add function by the result from the subtract function. Please make sure that division by zero does not occur, print error message instead. Use a PHP function (from PHP library). Ideally, this function would work with at least one other function from previous requirements or would add functionality to our current program. All of this should be in PHP (but you probably already knew that).

Hey! Here is the code for the above question.

<?php
         
         function addFunction($num1, $num2) {

            return ($num1 + $num2);

         }

         function subtractFunction($num3) {

           return (20 - $num3);

         }

          function multiplicationFunction($num1,$num2,$num3) {

           $result = addFunction($num1,$num2) * subtractFunction($num3);
           return ($result);

         }
    
         
?>
