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
Muscles of the thumb the other four fingers. The flexor pollicis brevis, which lies next to the abductor, will flex the thumb, curling it up in the palm. The opponens pollicis lies deep to abductor pollicis brevis. As its name suggests, it opposes the thumb, bringing it against the fingers. This is a very important movement, as most of human hand dexterity including grip comes from this action. The abductor pollicis brevis originates on the scaphoid tubercle and the flexor retinaculum. It inserts to the radial sesamoid bone and the proximal phalanx of the thumb. It is innervated by the median nerve (C8 and
