Finger binary this is (512 + 256)/1024 = 768/1024 = 3/4. If using only one hand (left or right), it would be (16 + 8)/32 = 24/32 = 3/4 also. The simplification process can itself be greatly simplified by performing a bit shift operation: all digits to the right of the rightmost raised finger (i.e., all trailing zeros) are discarded and the rightmost raised finger is treated as the ones digit. The digits are added together using their now-shifted values to determine the numerator and the rightmost finger's original value is used to determine the denominator. For instance, if the thumb and
Thumb tip as an actor. Magicians have used modified thumb tips to accomplish different effects. A thumb tip with a slit in the tip can be used like a dye tube to apparently change the color of a silk . In this case, a colored silk is preloaded into the tip. The magician steals the tip into the left fist, then pokes a white silk into the tip while alternately pulling the colored silk out from the other end. A thumb tip with a small suction cup attached to the tip can be used to create the illusion of floating small objects
