1000000
1,000,000 (one million), or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one.
1,000,000,000
1,000,000,000 ("one billion" on the short scale; "one milliard" on the long scale; one thousand million) is the natural number following 999,999,999 and preceding 1,000,000,001. With a number, "billion" can be abbreviated as b, bil or bn.
googolplex
A googolplex is the large number , that is, raised to the power of a googol. If written out in ordinary decimal notation, it would be followed by a googol (10100) ‌a physically impossible number to write explicitly .

billion
Billion is a word for a large number, and it has two distinct definitions: 1,000,000,000, i.e. one thousand million, or (ten to the ninth power), as defined on the short scale (also known as a milliard on the long scale). This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in Britain and other English-speaking countries as well. 1,000,000,000,000, i.e. one million million, or (ten to the twelfth power), as defined on the long scale (that is, a trillion in the short scale). This number is the his

hyperoperation
In mathematics, the hyperoperation sequence is an infinite sequence of arithmetic operations (called hyperoperations in this context) that starts with a unary operation (the successor function with n = 0). The sequence continues with the binary operations of addition (n = 1), multiplication (n = 2), and exponentiation (n = 3). After that, the sequence proceeds with further binary operations extending beyond exponentiation, using right-associativity. For the operations beyond exponentiation, the nth member of this sequence is named by Reuben Goodstein after the Greek prefix of n suffixed with -
