Instructions for the Algebraic Calculator for Three Unknowns
The Algebraic Calculator for Three Unknowns solves three equations for X, Y, and Z. The equations must be similar to AX+BY+KZ=M, DX+EY+FZ=N, and GX+HY+JZ=W, such as the following examples
2X+3Y+5Z=10, 1X+4Y+7Z=18, 9X-4Y+6Z=22
-X+2Y-9Z=24, 8X+6Y+12Z=33, 2X+9Y+14Z=36
77X+56Y+45Z=130, 66X+34Y+19Z=68, 35X+32Y+21Z=88
2X+3Y+4Z=0, 1X-6Y-9Z=6, 3X+2Y-7Z=-4
If the equations you want to solve do not look like the above, try to algebraically rearrange them to make them similar to: AX+BY+KZ=M, DX+EY+FZ=N, and GX+HY+JZ=W.
Note: If less than 12 numbers are entered the Algebraic Calculator for Three Unknowns may not function properly. The Calculator has a number of error-checking devices that may display error messages while entering numbers, which may continue until all 12 numbers have been entered.
If you entered a set of numbers that do not satisfy all of the equations in the Algebraic Calculator for Three Unknowns, you may get error messages that relate to one or more specific equations.
The spreadsheet versions of the Algebraic Calculator for Three Unknowns require either Microsoft Excel, or the free OpenOffice.org software package, (available from www.OpenOffice.org). In addition, Microsoft Windows is required for the spreadsheet versions.
Note: If you do not have Microsoft Excel, download the OpenOffice.org software package, because it is free and it is almost as good as the Microsoft Office suite. To download go to www.OpenOffice.org or left click on these words.
This website was designed to maximize efficiency and ease-of-use (usability, user-friendliness). The text is presented with large fonts. The paragraphs are relatively short, and the sentence structure and wording were written to maximize *comprehension. The website has a very simple layout, on a single page. This makes it easy to navigate intuitively, by scrolling down or up. All the links for downloads and other websites are also written with large fonts, and clearly marked as links, such as with the following words: left click on these words.
*Note: The material on this website and the Algebraic Calculator for Three Unknowns is technical. A background in mathematics and spreadsheet software is required for maximum comprehension. However, most individuals, without the technical background, will probably understand most of the material, if they have studied algebra.
I design and build user-friendly software based calculation devices for arithmetic, accounting, currency exchange rates, algebra, trigonometry, correlations, calculus, and databases with built-in calculation devices. I also create attractive online calculation devices, and web communication forms for websites. This includes website forms with built-in calculation devices.
I write instructions for the devices I build. I can also write instructions for software and computer devices created by others. In addition, I can write advertising for your websites, products and services.
