This app is a quiz application that determines whether a number is prime or composite and swipes the correct answer. A prime number is a natural number greater than 1 that is not divisible by any other number except 1 and the number itself. For example, 2, 3, 5, and 7 are single-digit prime numbers. Composite numbers (composite numbers) are natural numbers greater than 1 that are not prime and are represented by the product of smaller natural numbers (e.g., 4 = 2 x 2, 6 = 2 x 3).
