The sum of a natural number n and its square equals the product of the first three prime numbers. What is n?
n + n^2 = (2)(3)(5)
n + n^2 = 30
n^2 + n - 30 = 0
(n - 5)(n + 6) = 0
n - 5 = 0 or n + 6 = 0
n = 5 or n = -6
Since -6 is not a natural number, the answer is n = 5 Remember: 1 is neither prime nor composite number, and 2 is the only even Prime number. -6 is an integer, but is not a natural number The set of natural numbers is: N = {1, 2, 3, 4,...} The set of whole numbers is: W = {0, 1, 2, 3,...} The set of all integers is: I = {..., -3, -2, -1, 0, 1, 2, 3, ...} The set of all Rational numbers is: Q = {a/b|a,b are integers, and b is different than 0} The decimal names for elements of Q are:
(1) terminating, (2) nonterminating with a repeating block Examples: 1/2 = 0.5 and 1/3 = 0.333...
The set of all Irrational Numbers is: S = {x|x has a decimal name which is nonterminating and doesn't have a repeating block} Examples of irrational numbers include 0.101001000..., pi and square root of 2 Q and S have no common elements. All these numbers are called real numbers.

What is the last digit in the product of the first 20 odd natural numbers?
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
Write the product of each pair of numbers?
The product of two numbers is the resulting number when they are multiplied together. As there is an infinite amount of numbers it would be impossible to write out the result of the product of all pairs of numbers
Can natural numbers be negative?
No. Natural number {1, 2, 3, ...}.
Is Natural numbers are closed under multiplication?
Yes.natural numbers are closed under multiplication.It means when the operation is done with natural numbers in multiplication the sum of two numbers is always the natural number.
What are counting or natural numbers?
Counting numbers are the positive integers: 1, 2, 3, and so on. Natural numbers are the counting numbers along with the number 0.
The product of two positive numbers equals?
A positive number.
Product of a natural number and every smaller natural number?
The product of a natural number and all of the lesser natural numbers is called the factorial of the number. It is often represented with an exclamation point. So:5! = 5 * 4 * 3 * 2 * 1
If the product of three numbers is 140 and two of the numbers are 2 and 10 What is the third number?
If the product of three numbers is 140, then we can write 140 as aXbXc. Let a be 10 and let b be 2. Then 140 equals 10X2Xc, or 7 equals c. Thus, the remaining number is 7.
When the product of two irrational numbers equals a rational number then what are the factors called?
They are called conjugates.
What is a pair of numbers whose product equals a given whole number?
That's a factor pair.
The product of a number and its equals one.?
The product of a number and 1 over that number equals one.
Why are prime number considered the building blocks of the natural numbers?
All natural numbers greater than 1 the product of 1 and one or more primes.
Is it true that when you multiply two natural numbers the product is never less than either of the two numbers?
Yes. Natural numbers are counting numbers, equal to or greater than 0. The only ways a product can be less than its multiplicands is when multiplying fractions by fractions or multiplying a positive number by a negative number.
What is the product of 41 and 63?
The product of two number is the result of the two numbers multiplied together. 41 times 63 equals 2583
The product of two or more nonzero whole numbers is?
well, its quite simple: it is a natural number.
Is the product of two natural numbers always a natural number?
Yes. Natural numbers, or counting numbers, cannot produce non-natural numbers, or complex numbers, through methods of multiplication or addition. However 5 divided by 3 creates the complex number 1.666666.... So division of two naturals can produce a complex. Also 6 minus 10 creates -4 which is not a natural number.
One of two numbers whose product is1?
Any number except zero. A number multiplied by its reciprocal equals 1.
