Well, its not that hard: Some machines help people do work by changing the size of the force needed. Have you ever tried opening a door by turning the shaft instead of the handle? Not as simple. It takes less force to use the handle instead of the shaft. If a machine (doorknob attached to shaft) allows you to exert less force, you must apply that force over a greater distance. the complete and total amount of work done remains the same, whether its by machine or not. Because a machine does not change the amount of work to be done, less force must mean greater distance. So: Machine=less force BUT greater distance!
It's a complex machine...

A machine's mechanical advantage is the number of times a machine multiplies the amount of work force you apply.

Your checking account is linked to a routing number that your bank sends to a credit company when you apply for a debit card. When you swipe your card in the machine and enter your pin, the credit takes the money in your account and gives you an equal amount out at the machine.

It is a simple machine which can be used to apply a relatively weaker force over a longer distance instead of a much greater force over a short, direct distance.
