A Must-Get Calculator

I bought this calculator, TI-36x Solar, last year, and I have not bought any other calculator since. It is so far the best calculator you can buy and it's not expensive either - $10 only!

The calculator features of course the basics - addition, subtraction, multiplication, and division. If you have trouble doing exponents, that's okay, because the calculator itself will do it for you. Other features, include changing positive to negative, parentheses, square roots, converting fractions to decimals, doing fractions, etc. (just to name a few).

I've always had the problem of doing a really long addition problem and always typing in the wrong key by accident. This calculator now features a button that you can press and it erases ('delete') what you just wrote if you mistakenly press in the wrong number.

I also love that it is run by solar power. It's such a pain in the neck to keep buying and then changing batteries every time the calculator starts dimming out. I personally hate it and that's why this calculator is so great by being run by solar power.

The people that might find this useful and probably a must-need is if you are in advanced algebra, doing statistics, chemistry, or trigonometry.
It's a reliable calculator that gives you all the scientific functions you need for those courses.

Overall, I would say that this IS the BEST and ONLY calculator I have ever bought and I know I don't plan on changing anytime soon.
