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
Touch typing must have been using similar systems. In 1889 Bates Torrey coined the words "writing by touch" in his article. In 1890 Lovisa Ellen Bullard Barnes defined the words "write by touch" in her book as follows: Touch typing is contrasted to "search and peck", also known as "hunt-and-peck" or "two-fingered typing". Instead of relying on the memorized position of keys, the typist finds each key by sight and moves their finger over to press it, usually the index finger of their dominant hand. This method is considered inferior as not only is it slower than touch typing, the typist would
