there is not "carrot" or anything if you want to put an exponent you hit the exponent button and type the exponent. that simple. The equations you type are typed as you see it, not as you program it. I hate calculators that you have to type something like
8^(1/3) to have a third root of 8. You can use two ways press the root button and type three (in the crack) and it will show up as the third root of 8 just as if you have written it down. Or if you are old fashioned like me and like to place an exponent instead you hit the exponent button and hit 1/3 and you will have an elevated 1/3 infront of the 8. you can type fractions as high as you want and equations pretty far. Like if you hit 8/8/8/8/8/8/8 you will have a very tall fraction in the calculator. Only downside is when you have two fractions next to each it doesnt take it as multiplication, all you have to do is hit multiply and youre good.
It has all your basic 3 trig functions and their inverse functions. It even has your basic 3 hyperbolic functions and their inverse functions. you can have log with any base. When you hit = and the answer can be written in fractions, it will do it for you! If you want it in decimals. just press a button. If you hit sin(pi/4) it will give you root(2)/2. I love that because i forget my trig sometimes on a test.
If you are an engineering major like me, you can get through all your mathematical courses with this calculator as your greatest tool. There are bunches of functions it can perform, I am not aquanted to all of them yet. Heck these calculators even compute matricies. I dont know how to do it very well though
I cannot oversell this beauty. I can hardly stand to use any other scientific calculator after getting used to this beauty!
In short, this calculator will serve you well. Inputting equations has never been easier thanks to it's "textbook display" which allows you to type down the equation exactly how you see it on your book.
Price: This calculator is inexpensive and nearly disposable. For the price, you are getting what you paid for.
- This calculator is not a graphing calculator, so if you need to graph lines then this calculator is not for you.
- This calculator is also not programmable, like adding your own equations into the memory bank and such.
- 40 metric conversions (the list of what you can convert is on the cover of the calculator. It was somewhat useful to me, but I doubt it's allowed on tests.
- The "natural textbook display" is a real plus for me. Writing down fractions has never been more easy and simple.
- Another problem I had with this but every time I get an answer it always comes out as a fraction, but I need it as a decimal so I have to push the S<=>D button every time I want to go from fraction to decimal. (-0.5 stars) I don't think I have found a way to change it automatically to decimal my default, but please comment on this if you have.
- The calculator is made of plastic, but has never broken yet after all the beating I've given it inside my backpack.
- The only thing I didn't like about this calculator is that there is no rubber on the outside of the cover or on the back of the calculator to stop it from sliding all over my table (for those who have slanted desks or moves a lot) and also uneven surfaces while pushing buttons on the calculator makes the calculator go up and down making loud "click-clack" noises which can annoy some people. (-0.5 stars)
Basically, I'm happy with my purchase. There's nothing special with this calculator and its as simple as can be. Just give it a day or two to get used to it and refer to the (large) instruction manual or the internet for help.
