Why Every Student Needs the Casio FX-991EX


So as you may know… or figure considering I'm writing for a blog… I'm a writer. And that means numbers are my natural enemy. Getting the chance to try out a newly improved high tech calculator was rather exciting because in the math department, I need all the help I can get.

It turns out the Casio fx-991EX is a great addition to any student's back to school list, or any person that really troubles with math… like me. It has a very simple, sleek design and is easy to use. It's also versatile and has plenty of uses. Here are i reasons why your daughter/son should invest in this calculator:

1.) High resolution. – The calculator has a very distinct, visible, bold font. It's crisp and easy to read… I don't know  how else to compare it other than saying a normal calculator would be like an iPhone 4 photo, and then the Casio would be more of a high quality Cannon photo. It displays twice the number of characters in its default size and six times the number in its smallest size compared to other calculators and previous Casio models. The screen is easy to read, and the buttons are very clear, and the layout is simple. Also, words are not abbreviated so you don't have to guess what mode you're setting your calculator into like I have done in the past. 

2.) Special features. – The Casio contains multiple special features. Physically, the keys are metallic, the functions are organized by color (red, yellow, white), and the notation is understandable by including images seen in text books. Mechanically, the special features include spreadsheets, equation solvers, and an online visualization service. I strongly suggest students taking the AP tests and such to look into this calculator because it can literally solve algebra for you and those moments saved solving basic math can really help out in the long run. Also, there's a delete button so instead of clearing everything you have on the calculator, you can simply backspace. The calculator is really easy to navigate. You can also convert your equations and formulas into a QR code that syncs with your phone or tablet to help understand more.

3.) Utilities. – On the Casio, you can determine base-n calculations. Additionally, there are 47 scientific constants, 40 metric conversions, and 9 variable memories. 

4.) Basic Functions. – Obviously you can add, subtract, multiply, divide, input fractions and mixed fractions, square roots and whatever to the power of this or that and so on… There's also trigonometric and inverse trigonometric functions, logarithm, and fraction problems. 

5.) Algebra, Probability, and Statistics. – Regarding algebra, the calculator truly excels. It performs equation calculations like I mentioned before which is essential if you're looking for an edge in math and especially if you're taking standardized tests. It can also solve inequalities, table functions, matrix/vector calculations, complex numbers, and prime factorization. Regarding probability, it can solve permutation and combination. Regarding statistics, it can perform statistical calculations and distributions.

Overall, this calculator is a slim, sleek device with many features. It can solve a wide variety of math as stated above. The layout is easy to read and the calculator is simple to understand and navigate. I've previously used Casio calculators and love them… This one especially will truly help sharpen your student in math by providing an easy resource to solve many problems.
