Code:
<?php
$penjumlahan = 2+4;
$pengurangan = 6-2;
$perkalian = 6*3;
$pembagian = 15/3;
$modulus = 5%2;
echo "Menampilkan hasil perjumlahan 2 + 4 = ".$penjumlahan."<br>";
echo "Menampilkan hasil pengurangan 6 - 2 = ".$pengurangan."<br>";
echo "Menampilkan hasil perkalian 6 * 3 = ".$perkalian."<br>";
echo "Menampilkan hasil pembagian 15 : 3 = ".$pembagian."<br>";
echo "Menampilkan hasil modulus 5 % 2 = ".$modulus."<br>";
?>
ntar hasil nya kayak gini
