Summary: Buy it used for calculate. It is thinner than I thought. What is more, it is lighter than the calculator I used before. It Even can calculate derivate. It is very powerful and convenient to use.
Summary: I will keep this short and sweet. At $14, this calculator is well worth the cost of replacing your outdated calculator as it processes, computes, and displays far better than those that might have cost you upwards of $50 to $100 years ago. Seriously, look no further...it's the way to go!
Summary: I bought this calculator because of price and reviews on amazon. I'm using it for a moderate level college algebra class. During some homework & a couple online quizzes, I kept getting a few problems wrong. I couldn't figure it out. I reviewed the homework, input the numbers carefully, made sure my answer matched the calculators but no luck.
Excerpt: This is my favorite scientific calculator, and I have been using this model, or the most similar Casio model to this one since about 1979. It got me through both undergraduate and graduate schools. In those 35 years this is only the second time I've had to replace it--and each time was just because the poor thing eventually wore out.
Summary: Stylish. Inexpensive. Fast ship. HOWEVER - the claimed staright algebraic input...NOT SO. Navigation through instruction booklet and on the calc itself are 'torture' and not intuitive. I would not want to have gotten this less than 6 months before an exam because that is how long the learning curve is.
