Excerpt: This is a great calculator! I have never purchased a HP brand calculator before but this is the one that my professor requested. Now I see why it was my professor's calculator of choice! It is sturdy and dependable. It is neither too big or too small. It has every function I need as an accountant. It really has no negatives and was affordable. I can find nothing wrong with this calculator and I would now consider HP as a solid choice for calculators from now on.
