Which term refers to a whole number multiplied by itself?

The term that refers to a whole number multiplied by itself is "Square." When a number is squared, it means that it is raised to the power of two, which is mathematically represented as (n \times n), where (n) is the whole number in question. For instance, if you take the number 4 and square it, you multiply 4 by itself to get 16 (since (4 \times 4 = 16)).

This definition is distinct from the other terms presented. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself, while a composite number is a natural number that has more than two positive divisors. Finally, a cube refers to a whole number multiplied by itself twice, represented mathematically as (n \times n \times n). Thus, the concept of squaring is specifically tied to the operation of multiplying a whole number by itself.
