If you are in grades 4-8 this is a wonderful graphing calculator to explore and formalize your understanding of the math concepts. It has many nice features. However if you need a graphing calculator that you will use through high school use the TI-83 Plus Silver Edition. If you are purchasing during your high school years you may want to consider even starting with a higher caliber calculator than this as a TI-83 Plus will not take you through very many college level math courses until you need something more substantial in available functions.

This is a great calculator for a Middle School/High School Student. There are many functions on this calculator that are really useful. Also, there are mini math games, such as probability, etc. Overall, ti-73 calculator is a great calculator if you're looking for a useful, long-lasting calculator because this is one of the best calculators around that I have used. Overall, I would recommend this product, as it has a very good quality.

So far, this has been great for my Precalculus class. I paid $50 to more that $100 less for it than my classmates paid for theirs. I'm happy so far! (I've only been using it for three weeks...) If I need to revise this opinion, I will... but as of this moment I'm happy with it.

Not only did I get my product faster than I expected to, I got it with fresh batteries and replacement batteries. I needed this calculator for college but did not want to buy the TI-84 model because of how expensive it was. I have been very happy this this and the merchant that old this.

If you need this calculator for basic math and algebraic solutions, it's perfect. For trigonometry and beyond it is worthless.

Great calculator...my son who is a junior in high school needed this for his honors accounting class as a regular calculators does not have all the bells and whistles like this graphing calculator does. Great product, pretty good price and shipped on time. Thanks
