Just learning Bitwise Shift Operators.

The easiest way to resolve a bitwise  shift operators is my multiply or dividing each step by two for left shift or right shift respectively

Example:

LEFT SHIFT
<?php echo 8 << 3; //64 ?>

//same as
<?php echo 8 * 2 * 2 * 2; ?>

RIGHT SHIFT
<?php echo 8 >> 3; //1 ?>

//same as
<?php echo ((8/2)/2)/2; //1 ?>

//Solving on a paper 8/2 = 4/2 = 2/2 = 1
