How much can you learn for 60 USD? You could take a couple of driving lessons, maybe, or buy a few books to read. If you’re on a tight budget but still want a good amount of functionality, the fx-9750GII is one of the best graphing calculators around. For a general mathematics course, this will be overkill, but it’ll get you through the first couple of years of a college-level program with no problems at all. This may not be the most expensive calculator out there, and it doesn’t offer the ability to solve algebraic problems like the more advanced ones do, but it’s still extremely powerful. This alone doesn’t make the calculator easy to use, though: it has a very clean navigational interface, so it’s very difficult to get lost in the menus when trying out a new function. This Casio uses an icon-based menu system, which helps to decrease confusion when switching between modes. The buttons are clear and well labeled too, so you’ll never have to guess as to what each of them does. This allows you to see graphs more clearly and therefore, better understand where exactly each data point lies. The display offers a higher resolution than most, too, at 128×64 pixels. The first set of batteries is provided with the product, but you’ll need to buy some more eventually, although each set should last you for about a year. It weighs just 7.5 ounces and requires four AAA batteries to function. This calculator is 6” tall, 4” wide, and one inch thick. Because it can’t connect to the internet, it’s permitted for use in various examinations such as the SAT, AP tests, and college entrance exams. You can also attach it to a second calculator and share your results with it – a transfer cable is included, but the USB cable is not, so you’ll have to locate one of those yourself. The fx-9750GII can connect to your computer using a USB cable, which allows you to backup your data. It’s even capable of handling larger, more advanced data structures, with a maximum matrix size of 70×70. Your results can be displayed as a pie chart, line graph, bar graph, or conic sections, which really adds to the versatility of this model. That said, you do have the choice of output graphs. It can solve simple equations but unfortunately lacks more advanced CAS functionality. On top of that, it excels at creating graphs quickly – it has 62KB of RAM, which is more than double what some of its Texas Instruments rivals have, and this means that you’ll spend far less time waiting for a graph to be produced. Converting decimals to fractions, using the financial function, generating statistics, you name it. It can do just about anything you’d ever ask for. It retails for around 45 USD, and it comes with a whole host of functionality that’ll make your phone’s calculator look like a children’s toy. However, they’re not all that expensive – take, for example, the Casio fx-9750GII. If the last calculator you bought was in high school, you’re probably blown away by how expensive some of the more advanced models are.
