- Scientific Notation
The scientific notation of a number is
that number written as a power of 10 or as a decimal number between
1 and 10 times a power of 10.
- When you multiply numbers, the numbers being multiplied are called
factors. The process of taking a given number and writing it
as the product of two or more other numbers is called factoring.
The result is called a factorization of the given number.
- A prime number is a natural number with exactly two distinct
factors. A composite number is a number with more than two factors.
Will any number besides 1 have fewer than two factors? The primes smaller
than 100 are here: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41,
43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97
