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).
