Questions & Answers
Q: What are prime numbers?
Prime numbers are whole numbers that cannot be factored into smaller whole numbers. They are the fundamental building blocks of all numbers.
Q: What are twin primes?
Twin primes are pairs of prime numbers that are two numbers apart, like 3 and 5, or 11 and 13. It is still unknown whether there are infinitely many twin primes.
Q: What is the significance of prime numbers in mathematics?
Prime numbers have numerous applications and are essential in fields such as cryptography, number theory, and computer science. They play a fundamental role in the understanding of mathematical patterns and structures.
Q: Are there numbers that are commonly mistaken to be prime but are not?
Yes, numbers like 57, 27, 51, and 91 are often mistaken as prime due to their appearances. However, they can be factorized into smaller whole numbers, making them composite numbers.
Summary & Key Takeaways

Prime numbers are numbers that cannot be factored into smaller whole numbers. They are the building blocks of all numbers and are fundamental in mathematics.

Prime numbers, unlike composite numbers, do not have any nontrivial factorizations. For example, 12 can be expressed as 6 times 2, but 5 cannot be further factored.

There is an infinite number of prime numbers, and they become rarer as numbers get larger. Twin primes, which are two primes that are two numbers apart, are an interesting subject of study in number theory.
