Answer:
Counting the number of school buses that pass Sam's house from 2 to 3 on Monday is an example of a basic counting operation.
Explanation:
Counting is a fundamental mathematical operation that involves determining the number of objects or occurrences. It is a simple and direct process of assigning a number to each item being counted. In this case, Sam is counting the number of school buses that pass her house within a specific time frame (from 2 to 3). She is assigning a number to each school bus that she observes during that period. Counting is an essential skill that helps develop a sense of number and is foundational to more complex mathematical operations such as addition, subtraction, multiplication, and division. Therefore, the mathematical operation involved in Sam's activity is counting.
