Then you can ask questions like: Find all of the points on a circle of radius $8$ that have a slope of $\frac{3}{4}$. so that they can explain their problem-solving. Even if they do end up using advanced calculators, they will ...

For example, the NY Times did a softball interview recently with Chegg's CEO, where they asked, "Many ...

The algorithms often do strange things that no human would do, which allows you to catch students who use them. For example I gave the following question: Use the comparison test to show that this series ...

Note: It's possible that in the future, Wolfram Alpha will improve and be able to answer the questions in this answer, so it's best to actually try them in Wolfram Alpha first. Use questions that involve conditional statements and generic expressions. For example: If $\lim_{x\to\infty} f(x)=1$, then what is $\lim_{x\to\infty}\frac{f(x)}{x}$ equal to? ...

They can be found by Googling the name of the subject and "exams", the name of the institution or the exercise. It's easier in languages ...
