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 and then finally the right thumb, which comes quickly out of the hand with the tip on, and the object inside, between the tip and thumb. While the audience is looking at the fist, the performer has chance to misdirect and dump the tip and contents in a pocket, perhaps under cover of putting the hand in the pocket to obtain some "magic dust" to sprinkle on the left fist. Alternatively, the tip may be kept on the thumb for an indeterminate amount of time, using techniques of misdirection and shading to keep it invisible to the audience. An appearance
