+// Now that we know how to create variables, let's look at doing some math.
+$a = 1;
+$b = 2;
+
+// To add two values, use the plus symbol.
+$c = $a + $b;
+
+// To subtract, use the minus symbol.
+$c = $b - $a;
+
+// To multiply two values, use an asterisk.
+echo $a * $b;
+
+// To divide values, use a forward slash.
+echo $b / $a;
+
+// PHP uses the percent symbol for calculating the modulus of two numbers.
+// The modulus is calculated by dividing two numbers and returning the remainder of the result.
+// So, in this example, the value of $modulo will be 0.
+$modulo = 10 % 5;
+
+// You can also use double asterisks to calculate a number to the power of another number.
+// The following statement will print 25.
+echo 5 ** 2;
