FutureStarrA Calculator That Shows Work App
What if there was a calculator that showed work? What if this calculator could calculate work, with no prior knowledge of mathematics or science required? What if this calculator could be used to calculate work on your own devices, from anywhere?
Unfortunately, no matter how good you are at memorization, if you don't use what you have memorized on a consistent basis, you will eventually forget what you once had memorized. And therein lies the problem for most parents when it comes to helping their children with their math and algebra homework -- the average parent has not used what they were taught as children often enough to retain what they now need to tutor their children.I greatly appreciate the accuracy and flexibility of this calculator. It's very nice that I can use variables and nest functions, and the functions never seem to completely "zero out" due to a failure of precision like most calculators that are available for calculating hyperbolic trig functions. Especially since I am working with special relativity, where almost every single "daily life"-scale velocity is unbelievably small compared to the speed of light, so I am usually working with fractions on the order of a few billionths or smaller.
We couldn’t help but notice all the students’ frustration over their math homework. Not only does it make school work dull and unexciting, but it also deters youngsters from seeking knowledge with the passion that they need to have. So for all the tired mathematical souls across the globe, we bring you a service that will hopefully boost your level and improve your skills in all-things algebra. Here is the online, free to use algebra calculator you’ve been waiting for.Homework Check: Our algebra calculator can help you check your homework. Simply enter your problem and click Answer to find out if you worked the problem correctly. Now, I hope you realize that if you simply put your homework problems into the calculator and copy the answer down, you’re cheating yourself in the long run because you haven’t really learned anything. In order to do well on your upcoming tests and quizzes, you need to understand where the answer came from. That way, you can find your mistakes and learn how to complete the problems correctly. That’s why we’re encouraging you to sign up for Mathway, a supportive tool which provides you with the complete steps used to solve each problem. Ask your parents about it – it’s much cheaper than tutoring and will be a good investment in your future. Just click View Steps on the answer page to sign up. (Source: solvemathproblems.org)
Also, you might need to use the inverse trig functions to solve problems. Some calculators have the inverse trig functions as actual buttons if not secondary functions of the trig buttons. Other calculators have a simple inverse [inv] button that you can push. To use the inverse button, you push the [inv] button first, and then you push the trig function that you want the inverse of. So, if you needed the inverse tangent function, you would push your degree value, then [inv], then [TAN]. In some other calculators, you will push [inv], then [TAN], and then your degree value. It's important to get to know your calculator, and this is why testing centers tell you to bring a calculator you are familiar with!Prepare for tests and quizzes by practicing extra problems. Simply locate a topic you wish to review in the Examples section of the calculator. An example problem will appear in the calculator. (If you’re confused by the notation in the box, click the Show button. This shows the problem in the standard mathematical format.) Solve the problem on a separate sheet of paper and write down your answer. Then check your answer using the calculator – just make sure the Select Topic section matches what you’re practicing. If you got the answer correct, great! If not, you’ll want to view the steps in order to find your mistake. Sign up for Mathway (or ask your parents to sign you up) and you’ll be able to find your errors and see how to complete the problem correctly. It’s definitely worth the investment as you can use this calculator to prepare for tests for the rest of the year.

Now if you put different logic gates together, you can make more complex circuits called adders. You feed into these circuits two binary numbers as their input and get out a third, binary number as your output. The number that comes out is the binary sum of the numbers you put in. So if you fed in the electrical signals 10 and 11 you would get out 101 (2 + 3 = 5). The basic ingredient of adder circuits is a pair of logic gates, working in parallel, called a half adder, which can do sums no more complex than (wait for it!) 1 + 1 = 2. One example of a half adder looks like this: For the last century or so, computers and calculators have been built from a variety of switching devices that can either be in one position or another. Just like a light-switch, they're either "on" or "off." For that reason, computers and calculators store and process numbers using what's called binary code, which uses just two symbols (0 and 1) to represent any number. So in binary code, the number 19 is written 10011, which means (1 × 16) + (0 × 8) + (0 × 4) + (1 × 2) + (1 × 1) = 19. The beauty of binary is that you can represent any decimal number with a series of switches that are either on or off—perfect for a calculator or a computer—like this:
Photo: This is what calculators looked like in the 1970s. Note the very basic 8-digit green display (it's called a vacuum fluorescent display) and the relatively small number of mathematical functions (all you could really do was +, −, ×, ÷, square roots, and percentages). What you can't see from this photo is how thick and chunky this calculator was and how big its batteries were. Modern calculators are far more advanced, much cheaper, and use a fraction as much battery power.So far we've had a very simple look at what's going on inside a calculator, but we've not actually got to the heart of how it takes two numbers and adds them to make a third one. For those of you who'd like a bit more detail, here's a slightly more technical explanation of how that happens. In short, it involves representing the decimal numbers we use in a different format called binary and comparing them with electrical circuits known as logic gates. (Source: www.explainthatstuff.com)
