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-shift keyboard they found it difficult to use. They then came up with an idea of using thumb in conjunction with other fingers. Unlike the shift action with little finger in English keyboard, in which shift key is pressed and held while a character key is hit, this method uses simultaneous hit by thumb and other finger. This has several advantages. First, it enables each key to be conjugated in three ways: without thumb action, with the same hand thumb and with the thumb of the opposite hand. This means that the keyboard can accommodate half as much more characters than in
