Here is my answer:

<?php

$number1 = intval(readline());
$number2 = intval(readline());
$number3 = intval(readline());
$endResult = addAndSubtract($number1, $number2, $number3);

echo $endResult;

function addAndSubtract($n1, $n2, $n3) {
    $result = 0;
    $result += $n1 + $n2;
    $result -= $n3;
    return $result;
}
