An example of an odd negative number is -7.

What is an example where two negative numbers multiply to give a negative number?

Normally, when you multiply two negative numbers, you get a positive number. This is because the negative signs cancel each other out. There isn't an example where two negative numbers multiply to give a negative number, as it contradicts the basic rules of multiplication.
Issa Rice
Can the product of two negative numbers be negative?

No, the product of two negative numbers cannot be negative. When you multiply two negative numbers, their negative signs cancel each other out, resulting in a positive product. This is a fundamental property of multiplication involving negative numbers.

Can the product of two odd integers be even?

No, the product of two odd integers cannot be even. When you multiply two odd integers, the product will always be odd.

Here's a simple explanation:

An odd integer can be represented as (2n + 1), where n is any integer.

Let's take two odd integers:

Odd integer 1: 2n + 1
Odd integer 2: 2m + 1

Now, multiply these two odd integers:

(2n + 1) * (2m + 1)

Expanding this expression, we get:

4nm + 2n + 2m + 1

This can be written as:

2(2nm + n + m) + 1

Since 2nm + n + m is an integer, the expression 2(2nm + n + m) + 1 represents an odd integer. Thus, the product of two odd integers will always be odd.

Can the product of two even integers be odd?

No, the product of two even integers cannot be odd. When you multiply two even integers, the product will always be even.

Here's a simple explanation:

An even integer can be represented as (2n), where n is any integer.

Let's take two even integers:

Even integer 1: 2n
Even integer 2: 2m

Now, multiply these two even integers:

(2n) * (2m)

Expanding this expression, we get:

4nm

This can be written as:

2(2nm)

Since 2nm is an integer, the expression 2(2nm) represents an even integer. Thus, the product of two even integers will always be even.

What is an example of a polynomial with rational coefficients?

An example of a polynomial with rational coefficients is:

P(x) = (3/4)x^3 - (2/3)x^2 + (5/2)x - 7

In this polynomial, each coefficient is a rational number (a number that can be expressed as a fraction with integers in the numerator and the denominator).

Give an example of a polynomial with rational coefficients that always takes integer values at integers

A polynomial that always takes integer values at integers is called an integer-valued polynomial. Here's an example of an integer-valued polynomial with rational coefficients:

P(x) = (1/2)x(x - 1)

This polynomial is actually a representation of the arithmetic sequence where the common difference is 1. When you substitute any integer value for x, you will get an integer result:

For example, let's substitute a few integer values for x:

P(0) = (1/2)(0)(0 - 1) = 0
P(1) = (1/2)(1)(1 - 1) = 0
P(2) = (1/2)(2)(2 - 1) = 1
P(3) = (1/2)(3)(3 - 1) = 3
P(4) = (1/2)(4)(4 - 1) = 6

As you can see, for each integer value of x, the polynomial P(x) yields an integer result.

Give an example of a polynomial with rational coefficients that are not all integers, such that the polynomial always takes integer values at integers

An example of a polynomial with rational coefficients that are not all integers, but still takes integer values at integers, is:

P(x) = (1/2)x(x - 1)

This polynomial represents the triangular numbers, which are the sums of consecutive integers from 1 to a given integer value. When you substitute any integer value for x, you will get an integer result:

For example, let's substitute a few integer values for x:

P(0) = (1/2)(0)(0 - 1) = 0
P(1) = (1/2)(1)(1 - 1) = 0
P(2) = (1/2)(2)(2 - 1) = 1
P(3) = (1/2)(3)(3 - 1) = 3
P(4) = (1/2)(4)(4 - 1) = 6

As you can see, for each integer value of x, the polynomial P(x) yields an integer result, even though one of its coefficients, 1/2, is not an integer.

Is the product of two prime numbers always prime?

No, the product of two prime numbers is not always prime. In fact, it is never prime (except for the special case when one of the prime numbers is 1, which is not considered prime by definition). When you multiply two prime numbers, the product will have at least two distinct prime factors: the two prime numbers being multiplied.

For example, let's multiply two prime numbers, 3 and 5:

3 * 5 = 15

The result, 15, is not a prime number because it has factors other than 1 and itself (3 and 5).
Issa Rice
Is the gcd of two distinct prime numbers always prime?

No, the greatest common divisor (gcd) of two distinct prime numbers is not always prime. In fact, the gcd of two distinct prime numbers is always 1. This is because prime numbers have no common divisors other than 1. By definition, a prime number has exactly two distinct positive divisors: 1 and the number itself. Since the two prime numbers are distinct, they do not share any divisors other than 1.
Issa Rice
Is 1 prime or composite?

The number 1 is neither prime nor composite. By definition, a prime number has exactly two distinct positive divisors: 1 and the number itself. Since 1 has only one distinct positive divisor, which is 1, it does not meet the criteria for being a prime number.

A composite number has more than two distinct positive divisors. As 1 has only one distinct positive divisor, it also does not meet the criteria for being a composite number.
Issa Rice
Is 1 positive?

Yes, 1 is a positive number. Positive numbers are those greater than zero, and since 1 is greater than 0, it is considered a positive number.
Issa Rice
Is 1 a positive integer?

Yes, 1 is a positive integer. Positive integers are whole numbers greater than zero, and since 1 is a whole number greater than 0, it is considered a positive integer.
