When Jeffrey walks, for every three steps forward, he takes two steps backwards.  Therefore, if the distance between the house and the mailbox is 66 steps, what is the total number of steps Jeffrey takes when he goes from the house to the mailbox?
For every 3 steps forward, he adds 2 more backwards so each 'step' gained costs 5 actual steps
66 steps distance * 5 steps moved = 
<gadget id="calculator">66*5</gadget>
