1. Let's clarify the question: Are we applying only positive values to the calculator? 2. In many math problems, especially those involving functions or equations, the domain (set of input values) can be restricted to positive values depending on the context. 3. For example, if the problem involves square roots, logarithms, or physical quantities like length or time, only positive values might be valid. 4. However, if the problem does not specify such restrictions, negative or zero values might also be applicable. 5. To determine if only positive values are used, check the problem statement or the function's domain. 6. If you provide the specific problem or function, I can help determine the valid input values.
