What different numbers are there in maths?
There is no end to the numbers of maths and there are many classifications of numbers, like primes, fractions, even, odd, positive, negative and others.
What number has the product of exactly three different prime numbers?
Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
How many even primes are there in 1 to 100?
Answer: 1, and that is 2?Answer: The only even prime number - nont only between 1 and 100, but among all the prmes - is 2. All higher even numbers are divisible by 2, and therefore not primes.
Find all pairs of consecutive prime numbers?
The only two consecutive numbers that are both prime are 2 and 3. Since there are no other even prime numbers (other than 2), there are no more pairs of consecutive prime numbers. Therefore, the term "twin primes" usually refers to pairs of prime numbers that are 2 numbers apart. Examples are (3, 5), (5, 7), (11, 13), (101, 103), and many others more. It is not currently know whether there are infinitely many twin primes.
How many odd prime numbers are there from 100-110?
Four. They are 101, 103, 107, and 109.Note:All prime numbers are odd, except '2'. All other even numbersare multiples of 2, so none of them can be primes.
How many even primes are there?
only one: 2.'2' is the only even prime number. All other even numbers have '2' as a factor.

Is the sum of two prime numbers always a prime numer?
It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.
How many groups of consecutive prime numbers are t(ere in the first 99 primes?
There is just one group: 2 and 3. No other primes are consecutive.
What number has the product of exactly three different prime numbers?
Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
What group of numbers even or odd contain more prime numbers?
All even numbers except 2 are divisible and thus not prime. There is no such number for odd numbers, and there is in fact just one even prime and infinitely many odd primes.
How many even primes are there in 1 to 100?
Answer: 1, and that is 2?Answer: The only even prime number - nont only between 1 and 100, but among all the prmes - is 2. All higher even numbers are divisible by 2, and therefore not primes.

How many prime numbers are there under 1000?
There are 168 prime numbers under 1,000 . There are also 25 primes under 100, 62 primes under 300, and 95 primes under 500
Is the sum of prime numbers cannot be a prime?
Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.
