Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
this calculator is horrible, my daughter is pretty advanced in algebra and coudn't use it, the fraction sign is missing and the company did not work with return
I have bought (2) of these calculators, but if you are not under direct lighting the entire time you are using this calculator it dies. I thought it was just the first calculator, but bought a second one and determined its the calculator. Casio has some way better calculators than this one, buy one of those or at least one that uses a battery too.
