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
This Old Man This Old Man "This Old Man" is an English language children's song, counting and nursery rhyme with a Roud Folk Song Index number of 3550. The origins of this song are obscure. The earliest extant record is a version noted in Anne Gilchrist's "Journal of the English Folk Dance and Song Society" (1937), learnt from her Welsh nurse in the 1870s under the title "Jack Jintle" with the lyrics: <poem> My name is Jack Jintle, the eldest but one, And I can play nick-nack upon my own thumb. With my nick-nack and click-clack and sing a fine song, And all
