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
Guidonian hand would indicate a series of notes by pointing to them on their hand, and the students would sing them. This is similar to the system of hand signals sometimes used in conjunction with solfege. There have been a number of variations in the position of the notes on the hand, and no one variation is definitive but, as in the example below the notes of the gamut were mentally superimposed onto the joints and tips of the fingers of the left hand. Thus "gamma "ut"" (two Gs below middle C) was the tip of the thumb, A ("A "re"") was
