Hi Ben,

Thanks for sharing this with us!

I took a closer look at this request and it looks like our exercises already have something like this, but I noticed that whether or not you need a calculator actually varies from question to question within an exercise set. So, we don't mark entire exercises as requiring a calculator or not because this can change depending on the question within the exercise set.

If a question will require the use of a calculator, you should see a calculator icon towards the top of the exercise.

If there's no calculator icon, then it's safe to say that the exercise is intended to be completed without using a calculator. This is not strictly enforced, however, so you are welcome to use a calculator as you please for your own learning, unless otherwise directed by your teacher.

I hope this helps! Please let me know if there's anything else I can do for you!
