What is a one-sentence summary of the following article?
Hold a stack of bills that are all the same denomination in your hand folded in half vertically so that all 4 corners are facing down. Secure the folded stack on either side with your thumb and pointer finger. Then, count as you rotate using each of your fingers and your thumb from the other hand to strike down against the folded stack and unfold 1 bill at a time. Pull down the 1st bill in the folded stack with your thumb, the 2nd with your pointer finger, the 3rd bill with your middle finger, the 4th with your ring finger, and the 5th with your pinky. Start again until you’ve pulled down and counted the whole stack. Use your thumb to hold a stack of bills that have the same denomination folded vertically in one hand with the corners facing up. Hold the back of the stack on the other side with your opposite pointer finger. Then use your thumb on this same hand to press down on the front of the first bill and pull it out from underneath the other thumb’s grasp by swiping laterally. Count while swiping each bill this way. Wrap a rubber band around the middle of a stack of bills that share the same denomination. Place the stack horizontally on a flat surface in front of you. Place your left hand on the left side of the stack with only your pointer and middle fingers extended. Grab the stack by the top right corner with your right hand and slide your right thumb to the left to pass 1 bill over. Count as you alternate between using your left pointer and left middle finger to grab each bill.

Summary:
Use your fingers to count in groups of 5. Pull each bill from your grip with your opposite thumb. Pass banded bills from one hand to the other.
