Somebody give me a 5 sentence answer on how to classify a fingerprint

Fingerprint identification is based on patterns recognition where the Arches loops and whorls of the fingerprint ridges are compared to store data. Once fingerprints are taken and labeled scientists use a classification system to identify them. There are more complex classification systems that further break down the pattern to plain arches or tented arches . Everybody has their own fingerprint it depends on the name birth date Arch Loop and whorl.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
