they are better than other scientific calculators because prime factorization can be done by these..
It is an improvement upon previous models of calculators, and the Silver Edition is just a fancy way of saying it is better. The TI 84 plus Silver Edition is a graphing calculator with a relatively large memory capacity and relatively fast processor.
The actual calculations to get a logarithm are quite complicated; in most cases you are better off if you look the logarithm up in tables, or use a scientific calculator.
http://www.algebrahelp.com/calculators/expression/oops/calc.do?expression=-6%281-w%29 This website solves all kinds of expressions. Do not go to edhelper.com! The best thing just look in you math book to find out and it will be better.
Scientific design is always better.

Income tax calculators for 2011 are available with many websites for free such as www.irs.gov/individuals/page/0,,id=14806,00.html, www.efile.com/tax-calculator/tax-estimator/, and www.calcxml.com/do/inc02.
One very good place to start is the instruction book that came with the calculator when you bought it. There are so many different kinds of calculators that no one book could show you which keys to push on several different calculators.
Savings calculators are useful tools for those wanting better control of their finances. Many banks offer savings calculators, while some smartphones have applications availble for use.
Division by zero is not allowed, an undefined operation. I've never seen a calculator display the infinity symbol, but it's probably better for the calculator to do that rather than display the message "You're not supposed to do that, dummy!"
The TI-89 is the better calculator. It has more functions than the TI-84, but is also more complex. Each is better for different situations or skill levels with calculators.
For basic algebra, you can use a calculator with basic functions on it used for arithmetic. If you are trying to solve more complex equations, a scientific calculator will suit you better.
There are tax calculators such as this one: http://www.efile.com/tax-service/tax-calculator/. If you need advice on whether you should file taxes quarterly or yearly, it may be better to go to a professional for help
The calculator is better at doing boring calculations than a human is, it solves most questions more quickly and accurately. This allows humans to spend more time doing what calculators can't (exerting creativity, formulating theories, etc.).
It keeps track of all the numbers. Instead of calculators that only show what you're doing, it'll show what you did. For example, a regular computer calculator doesn't show you what you punch in. After you punch in 463 + 1, the second you press another number, that first number goes away, so you have to get a better calculator, or recalculate. With a scientific calculator, you get a ride variety of buttons to help with different types of equations, and you have (on most) the ability to go back and check your question, and the ability to manipulate past numbers/signs.
144/12 = 12 and 432/27 = 16 So the better buy is 12 calculators for 144
3.732 x 10¹37.32 = 3.732e+1That's the way some calculators express scientific notation, but the first answer is correct and a better choice.On most calculators superscripts aren't an option and there also would be no confusion regarding "e" -- it doesn't represent e, the base of natural logs -- a problem encountered were scientific notation written this way anywhere other than a calculator.Why correct a correct answer; there are enough unanswered questions.
