Recently, I was hired to be a part-time tutor at my local learning center. Nevertheless, my spouse bought this calculator online for me because the one I had was out of batteries. I must say that I love knowing that I never will have to change the battery because it is solar powered! Awesome! I think this calculator is quite easy to use. I tutor algebra two and it can find a large number's logs and do exponents easily. I never have to struggle with this calculator; the buttons are easy to press and the display is very cear and easy to see. I also like how this calculator comes with a "help" sheet attached to the lid. It shows you how to enter in various functions. My old calcuator did not have this! But, I have to say that I dislike how this calculator does not have 2 rows of display, so you can not see what you plugged in, which can cause some problems if you enter in numbers too quickly. Be careful!
