Question

which set does not contain $-3$?\
the set of all integers\
the set of all rational numbers\
the set of all whole numbers\
the set of all real numbers

Explanation:

Whole numbers are defined as the set of non-negative integers: $0, 1, 2, 3, ...$. Integers include all positive and negative whole numbers plus 0, so $-3$ is an integer. Rational numbers include all integers (since integers can be written as $\frac{n}{1}$), and real numbers include all rational numbers. Thus, $-3$ is not in the set of whole numbers.

Answer:

the set of all whole numbers
