Mathematical application which able to work out simple algebra equation.

## User guide

To operate the game, press the back button, otherwise user will be able to write up numbers in the 100's, rather than the 10's.

Once the variable reaches 4, user can no longer make input, until select an operator, which is represented by a number. Only addition is supported.

If user wants a number that uses 10's digits, type as normal, if user wants 1's digits, press 0 first. The application will automatically switch to the next square after typed in 2 numbers.

The final square is for the answer of equation.

i should mention that pressing any non number buttons when you havent typed 0 before a single digit number will result in it being repeated.

anyways, press A, and at the bottom of the botom screen a number will apear, this is the value of X.

An example, to try out, is 3 + 5x = 13.

In this, x = 2, because 3 + 5 x 2 is 13 (2x5 is 10), which is basic math.

In that equation, the value of x will come out as 2.

Lastly, remember this only works for equations that use "+" and positive numbers, despite the fact i have +,-,x and divide, avaliable, these do nothing, also, this kind of equation would eve rhave x or divide, simply because it isnt practical.

## Controls

Up/Down - increase or decrease the number in the box

A - confirm

Control with Stylus.

- "1" button - divide by 10
- "10" button - multiply the number in the box by 10, to make reaching large numbers quicker.
- "get X" - change the "x" into the value of X

## Changelog

**10/9/2011 updates**

- Bbecause the background interferes with the value of x where it is, x is now redrawn on the top screen.

**9/05/2011 (1 hour after) updates**

- Now values increase when the button is held
- The value of x is redrawn on the top screen for easy readability

**9/05/2011 updates**

- Updated 0.2A now to support decimals! The gui though will need to change though to fit floats
- It was impractical to do otherwise, since the ds automatically removes the decimal numbers . e.g 1.5 = 1, 2.5 = 2 and so on.
