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 object to appear in the left fist after previously showing it empty. The right hand approaches the left and after a brief pause pulls out the silk handkerchief bit by bit from the fist. These appearances and disappearances are achieved by a small flesh-colored imitation thumb tip, usually made of plastic, rubber or painted metal, which fits loosely over the thumb. Space exists between the thumb and the tip into which a small object can be concealed. For the vanish, the tip is already in the left fist. The handkerchief or cigarette is pressed into the tip with the fingers
