More and more devices are using iOS 8 over iOS 7, and that means more and more developers are adding iOS 8-friendly features to their apps, especially widgets. However, not every widget available for your Notification Center right now is awesome. Take for example the Dropbox widget—it's essentially nothing more than a real-time notification, as the only action it performs is opening a recently updated file within the app.
Perhaps not as easy as using a calculator, but easy nevertheless! With mathematics, as with anything else, not everyone progresses at the same rate. Happily, in the age of Internet video tutorials, this isn't a problem. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. With this free video math lesson, you'll learn how to find square roots by hand.
In this tutorial, we learn how to find the area of a circle. The line from the middle to the edge of the circle is called the radius. Find what this is in your equation, then multiply (3.14 X radius x radius). This will always work out the area of a circle for you. So, do this equation with your calculator or by hand, then you will have the correct answer for the area. Make sure to add the units squared after you get the answer. If you are given the diameter (line all the way across), you wou...
In this video we learn how to convert recurring decimals to fractions. Start off by writing out the decimal with the dot next to it to show that it's recurring. This means that the number goes on forever and doesn't stop. To convert this to a fraction, write down the number as the numerator. On the bottom you will put the number 9 always. Now, you can divide these two numbers with each other using a calculator. Once you do this, you will get the correct answer. Once you divide it out, you wil...
In this video, we learn how to find the area of a trapezoid. The formula to figure out how to find the answer is: Area= 1/2x (base1 x base2) x height. Now, find the bases and the height of the trapezoid. Remember that the height must always be perpendicular to the bases. Once you have found these, add the bases and multiply by the height. You can use a calculator to do this or do it off hand if you're good with math. For the third step, divide the answer by 2 and then write down the answers w...

The video is a tutorial in trigonometry. The teacher teaches that the tangent or the tan of an angle is the ratio of the opposite side to the adjacent side of a right angled triangle. If one side and one angle is given then the value of the unknown side can be found by solving the equation tan of angle is equal to opposite upon adjacent side. If the angle is to be found then the tan inverse of the value is seen in the calculator.
In this video tutorial the author shows how to use the Cosine Law. He shows how to find an angle of a triangle where he know all the sides of a triangle, using the cosine Law. He uses a lower case letter to designate a side and a capital letter to designate an angel apposite to that side. He gives the formula for the cosine law using a triangle as an example. Now he goes on and demonstrates how to use a scientific calculate. He shows how to use the degree mode in the calculator to solve these...
Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.

Apple's Calculator app received a massive redesign, making it so much more than a simple calculator with built-in scientific functions. There's a new Math Notes feature that ties in with the Notes app, it can keep a history of your calculations, and you can even convert over 200 currency and measurement units.
The Calculator app is probably one of Apple's most-used iPhone apps, yet I always meet people who don't know all the little tricks there are to using it more efficiently. You may know most of them, but there's a chance you don't or at least forget about some of them.
There is no iPad version of Apple's Calculator app (at least, not yet), so you won't find it on your Home Screen, in your App Library, or as a shortcut in the Control Center. But that doesn't mean your iPad doesn't have an official calculator.

The AMOLED display on the Nexus 6 wastes no power to show black pixels. This is because pixels on such a screen emit their own light, and black can be easily achieved by simply not lighting any given pixel.
Apple is set to release its latest operating system for iPad, iPhone, and iPod touch this fall, and if you haven't noticed yet from our iOS 7 softModder guides, it's going to be pretty slick.
Nothing beats a human translator, but Google Translate and other software-based solutions have developed into decent alternatives for help with basic translations. Need an English word translated into German? No problem — but what if you need to have a conversation with someone who doesn't speak your language? Is Google Translate capable of doing that? The answer is not really.
Apple doesn't include its Calculator app on the iPad and never did. One almost appeared over 12 years ago but was nothing more than a blown-up version of the iPhone app. Since then, the company still hasn't made an iPad-optimized calculator, and there is no shortage of third-party alternatives to fill the gap. It may happen one day, but for now, these are the best calculator apps for your iPad.
One of the best things about iOS 7 is the Control Center, which gives you quick access from anywhere on your iPhone to turning on or off Airplane Mode, Wi-Fi, Bluetooth, and more. It also makes it very easy to adjust the brightness of your display, and gives app shortcuts for your Flashlight, Calculator, Timer, and Camera.
One of the more challenging things about using the Samsung Galaxy Note 3 is the ability to use it with one hand, due to its enormously large (but wonderful) screen size.
Math is one of those subjects in school where you either love it or hate it or just don't get it. But math is nothing to fear, because it's a part of our everyday lives, and ifs something everyone should know the basics of. Don’t let math intimidate you. Whether you’re multiplying two fractions or a fraction and a whole number, solve the problem without a calculator in just a few steps.
As I've explained before, black app backgrounds save you a bit of battery life on your Samsung Galaxy S5. This is because the AMOLED display on your S5 does not have to power pixels or a backlight for portions of the screen that are black.
Before the calculator and even the abacus was invented, there was a little instrument called the human brain that we used to do math. Remember that? While most of us turn to our trusty Ti-84s to do calculus homework or whip out our cell phone calculators to determine how much we should tip at Johnny Rocket's, it can often be much faster to use our own brains, along with a piece of paper and pencil.
It seems like everyone is getting in shape these days (or at least trying to improve their fitness), and as a result, there's an endless supply of fitness trackers and smartwatches hitting the market. This is all very wonderful, unless of course, you're broke and can barely afford a decent pair of running shoes.
Math homework isn't the easiest thing to get through quickly, no matter how prepared you are. Knowing your stuff simply won't cut it. Going through dozens of equations in one sitting could take up hours of your time. Even when you finish, there's always going to be that one problem you couldn't solve, which could take hours itself to finally get right.
