Mathematics Integer Question

[Boomwebsearch]

On a number line, let point P represent the largest integer value that is greater than √201. Let point Q represent the largest integer value that is less than -√20. What is the distance between P and Q? I am asking this off-topic question to see if anyone knows the answer and can help me by letting me know. I am trying to review some algebra and integer concepts that I learned a long time ago.

The largest integer value greater than any given bound is infinity. Assuming you mean the smallest integer value greater than √201, you know that √201 is between 14 and 15, so the value that you are interested in here is 15. The largest integer less than -√20 is the largest* integer less than -4.something, so -5. The distance between two points on an axis is the difference between them, so 15--5 = 20.

 

*largest typically refers to the magnitude of a number, so the answer would be negative infinity here, but I'm making the same assumption as in the previous part.

Thank you for responding to my question, also your assumption that you made in your post was correct. Therefore you have successfully answered my question!
