👉 Exactness in mathematics refers to a property of a mathematical statement that is verified by an algorithm or computer program. In other words, it means that if we run the program with all possible inputs and check its output, it will always return the same result as if it were true. For example, consider the following mathematical statement: ```python def test_function(): for i in range(10): print(i) ``` If we ran this code on a computer, it would output
