Define factors, multiples, prime numbers, variable, and reciprocals.
Answer:
A factor is a divisor of an integer; for example, 1,2,4,8, and 16 are factors of 16. Zero is not a factor of any integer.
A multiple is the product of an integer and another integer; some multiples of 4 are 4, 8, and 12. 2 is not a multiple of 4; 2 is a factor of 4. Zero is a multiple of every integer.
A prime number is a positive integer which is divisible by only itself and 1, such as 2, 5, 11.
A variable is a letter, such as x or n, that is used to represent an unknown quantity.
The reciprocal of a non-zero number is 1 divided by the number. The reciprocals of numbers between zero and one are all greater than one. The reciprocals of numbers greater than one are all between zero and one.
