Prime Time: Math Adventure is appropriately named Prime Time. In this mode blocks containing numbers constantly ascend the screen. The student must select blocks which represent factors of the product numbers on the screen. Prime Time exemplifies the fundamental theorem of arithmetic, also called the unique factorization theorem, which states that every positive non-prime integer can be written as a unique product of primes.

This application illustrates the notion of an integer’s factors, and of the related property of integers called primeness, or primality. An integer is called prime if it is the product of only one distinct pair of integers. For example, 11 is prime because the only pair of integers whose product equals 11 is 1 and 11, as in 1*11 = 11 .
