In this math tutorial, you'll be trained in the arcane art of adding and subtracting rational expressions by finding the common denominator. A skill many discard upon leaving middle school, it is used by the villians who operate under the acronym "SAT" to test those caught blank minded and whose minds are unrationalized.
Learn how to add rational, or fractional, numbers by following the tutorial in this video. In the case of fractions where the denominators are the same, the addition is simple: you simply add the numerators and keep the denominator the same. When the denominators are not the same, you need to find the least common denominator (or multiple). Take a look at your denominators and test different numbers to find the smallest multiple of the two. Then, convert the two original fractions so that the...
Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...

Place the card in the center tip of your middle finger. The card should balance on your finger and you can test this by wobbling the card on your finger left and right without it falling off of your finger. Try to spin the card with your other hand. If it falls off your finger it may have been off center. Next, use your thumb, placed on top of the card to stabilize the card. Raise your thumb above the card. With your index finger, lightly pull the card toward your palm and generate a spinning...

In this how-to, viewers will learn how to create a presentation which fades in and out among still photographs using Flash animation. First, each image is given its own layer in Flash. Then the images are converted into movie clips. A motion tween is created among each image and a few blank frames, to create the affect of a slow fade in and out. Then the layers are distributed sequentially on the Flash timeline so that as each layer fades out, the next fades in. The finished movie is tested, ...
