The NLVM: Algebra Balance Scales (with Negatives) is an excellent resource for visually understanding the concept of keeping equations "balanced." Reproduce the equation given, by dragging the necessary blocks (positive) or balloons (negative) to each side of the scale. Once balanced, begin to solve the problem.======

Use the operations available to you to solve the equation. Choose an operation button (ex., subtraction) and in the blank provided, type what part of the equation that operation will be performed on (ex. 2x),hit Enter, and the application will perform that operation to both sides of the equation, and update to show the current state of the equation after that operation was performed. Users can even input their own equation using the "Make an equation yourself" option. This is a great tool to aid in structuring the equation-solving process, and keeping track of work done at each step. Does not work well in Firefox for the Mac OS, but seems to run fine in Safari.======

Use the operations available to you to solve the equation. Choose an operation button (ex., subtraction) and in the blank provided, type what part of the equation that operation will be performed on (ex. 2x), hit Enter, and the application will skip a line, and wait for the user to update the equation manually. It will notify the user whether each step is correct or not. Users can even input their own equation using the "Make an equation yourself" option.
