### Is it possible to calculate factors using a TI-30x IIS

I believe factors can be calculated on any basic calculator. Starting with 1, increasing by 1 until you get to square root (number) + 1 Let's do an example. 28 square root (28)+1 = 6 Factors 1, 28/1=28 2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal) 3, 28/3=9.33333 - not a factor - doesn't go in evenly 4, 28/4 =7 5, 28/5=5.6 - not a factor - doesn't go in evenly 6, 28/6=4.66666 - not a factor So now we can list our factors - 1, 28, 2, 14, 4, 7 Putting them in order, we get 1, 2, 4, 7, 14 and 28. Good luck, Paul

### How do I convert 0.1 into a percentage using a TI-30X-IIS?

Using any calculator, multiply it by 100. I think of "per cent" is "per 100" so you need to move to decimal two places to the right or multiply by 100. In this case, either way, we get 10%. Any questions, let me know. Good luck. Paul
