VolcanoCam 0.8 Beta
VolcanoCam - A view of Mt. St. Helens from the web cam at the Johnson Ridge Observatory. more>> Basic Algebraic Expressions and Algebraic Fractions - AlgeBasics
Algebraic terms, Notations in Algebra, Simplifying Algebraic Expressions, Algebraic Fractions and Indices
Tutorial
Introduces the rules for basic algebra - the multiplication and division of algebraic terms, followed by the concept of addition and subtraction. Teaches the easy way to remove brackets. The methods can be applied to all sums, both easy and complicated ones, unlike some methods which are only suitable for simple sums.
Simple mental exercises at the end of each session help to strengthen the concepts learnt.
It also teaches addition, subtraction, multiplication and division of algebraic fractions and indices.
Practice
AlgeBasics is capable of generating thousands of sums on algebraic expressions, algebraic fractions or indices for drills to ensure that the student masters these very important basic skills in algebra.
Algebraic Expressions
It includes sums on addition and subtraction, multiplication and division, order of calculations, removal of brackets and simple indices such as 2b2 x 5c x 3b.
The sums get progressively more difficult if a student is doing well. If a student is doing badly, the numbers will be kept simple to let him focus on the concepts.
Algebraic Fractions
Includes addition, subtraction, multiplication and division of algebraic fractions. Simplifying algebraic fractions by cancelling and removal of brackets.
Indices
Includes addition, subtraction and multiplication of positive indices and miscellaneous sums requiring a combination of these methods.
Worked Examples
More than 150 worked examples provide help for students who have difficulty in doing the sums.
Reports
You can print out a report at the end of each practice session. The report shows each sum with its correct answer and the students answer marked. It also includes the percentage score, the average time taken to do each sum and other details.<<less

Apple Video Player 1.7.2
Apple Video Player is made to view and control video using your Mac more>>
AVP supports NTSC, PAS, and SECAM video standards and it allows you to assign a description to each channel.
It also supports movie compression, closed captioning, and Teletex reception (Europe only). Version 1.7.2 fixes a frame freeze problem with QuickTime 3.
Main features:
- This document provides important information about the Apple Video Player software. You may want to print this document and keep it with your manuals. Most of this information is not in the documentation. If you have questions that are not answered in this document, refer to the manuals that came with your computer.
- Video viewing and video capture is supported in window sizes of up to 640 x 480 pixels. For the highest-quality video and TV viewing, use the standard video window sizes (Smallest, Normal, or Largest) in Apple Video Players Windows menu. If you choose to customize the window size (by choosing Other in the Windows menu), the images resolution may decrease.
- In addition, video resolution is optimized when you view the Apple Video Player video window on the monitor connected to the monitor port on your Macintosh. You can drag the video window to a secondary monitor (connected to an expansion card), but the image resolution will decrease.The Apple Video Player application program allows you to use a keyboard shortcut, called a "hot key," to open and quit the program, and to switch between Apple Video Player and any other open programs. However, due to a minor incompatibility problem with MacroMedia Director, the Apple Video Player hot key doesnt work when MacroMedia Director is open.
- If you are installing Apple Video Player for the first time, no hot key is defined. You can set one using the Hot Key item in the Setup Menu. If you are replacing a previous version of Apple Video Player, the hot key setting is retained in the Apple Video Player Preferences file.f you have a TV tuner card, the Apple Video Player application program can display closed captions for TV channels that provide them. However, in order for closed captions to be visible, the video window size must be set to Normal Size or greater. Also, for best results, networking or printing should not be active when close captioning is selected.Likewise, for best results, networking or printing should not be active when you are recording video from either television or an alternate video source. Virtual memory should also be turned off when capturing video for best results.
- Movies are captured at the current volume setting. Set the volume to the desired level before recording a movie. Movies recorded when the sound is muted will not have any sound.
