Numbers

Decimals can be positive or negative.

Multiplying by a reciprocal

Quite the opposite.

All natural numbers are rational.

None of them are irrational.

The possession of only two factors.

It is @#*&

Any pair of consecutive integers is co-prime.

No. It is 13*13

No, because every other number in the number line is odd so therefore if you have any number of consecutive numbers you will have at least one odd number (if you're talking about consecutive numbers on a number line).

They are:

13 17 19 23 29

31 37 41 43 47 53 59 61 67 71

73 79 83 89 97

Not necessarily. The prime factorization of the composite number 10 is 2 x 5. Composite numbers have three or more factors.

Well, two prime numbers added together to equal six are 3 and 3, and 5 and 1.

Two prime numbers multiplied together to equal six are 3 and 2.

2 x 2 x 5 x 7 x 11 is the prime factorization of 1540.

No.

1.4142135

You cannot divide by zero. The answer would be undefined.

Well, you wouldn't kill anyone by doing so, but you wouldn't accomplish anything either.

55

8 times 6

2.500

cuz 1, 2

Because they are both multiples of two, so when they're added, the sum must be

another multiple of two.

(One group of twos plus another group of twos must be a new group of twos, just

like one group of cows plus another group of cows must be a new group of cows.)

There are none.

It is 18607, as in the question.

No.

No because it has more than two factors

Yes.
