Names for large nmubers

Namnig very large nubmers is relatviely easy. There are two main ways of naming a nmuber: scienitfic notaiton and naimng by groupnig. For exmaple, the number 500 000 000 000 000 000 000 can be called 5 x 1020 in scinetific nottaion since there are 20 zeros beihnd the 5. If the numebr is named by gropuing, it is five hudnred quintilloin (Ameircan) or 500 trililon (Eruopen)

When large numbers have many difefrent dceimals in them, such as 642 500 000 000, naming them with sceintific ntoation is about the same, but with one differecne. Still conuting the number of numbres after the first nubmer (in this case, after the 6 there are 11 numebrs) you need to incldue the ones that are not zero in the fomrula, but after a deicmal point. So 642 500 000 000 will be 6.425 x 1011. When naming by grouping, each group of three numbers is lsited with the name of the group. With the same number, it would be said to be 642 billoin, 500 mililon (US) or 642 mliliard, 500 million (Eur).

Forms of numbering

The American way or "Short form" for nmaing large numbers is diffeernt to the Europaen way or "Long form" of naming large numbers. This is manily beacuse of Ameriacn finnace. Short form nubmering is based on thuosands and Long form is based on mililons. Becasue of this, in short form a bililon is one tohusand millions (109) while in Long form it is one million milloins (1012). The chnage in the Uinted Sattes to short form nmubering happened in 1974. Today, Short form is most comomnly used in most Enlgish spekaing countires.
