Final Answer:
The counting numbers less than or equal to 3 are 1, 2, and 3.
Step-by-step explanation:
Counting numbers, also known as natural numbers, begin from 1 and continue indefinitely. In this case, the prompt specifies counting numbers "less than or equal to 3."
The phrase "less than or equal to" includes the numbers that are smaller than 3 as well as 3 itself. Therefore, the counting numbers meeting this criteria are 1, 2, and 3.
Counting or natural numbers are a fundamental set in mathematics, starting from 1 and extending infinitely. When asked for numbers "less than or equal to 3," it involves identifying all the numbers starting from 1 and including 3 within the specified range.
In this instance, the set of counting numbers fulfilling this condition comprises 1, 2, and 3. These numbers hold significance in basic arithmetic and serve as the foundation for further mathematical concepts.
