If you still worry about failing to finish your math homework on time and missing the baseball league tonight, you might find some assistants to give a hint. We hate math, so do you, especially linear equation part. It’s too annoying to face over a mess of numbers and XYZs. Seize the time and never let it slip away. Well, with this homebrew called Linear Equation Calculator for Nintendo DS, things will get much easier to deal with.

You can find it on the arthor TAROSA’s homepage. Unzip the file and copy them to your TF, open your DS and launch the sesolver.nds. It’s in Japanese but still very easy to use, let’s look it up step by step.

On the first picture you will see the basic control and hotkeys. Then touch the botton screen to begin.

Then choose linear equations you want to solve (maxium to Quintic), for example, we will conquer a linear equation in two variables, so choose 2 and touch ENTER.

When finishing input all parameter of the first equation, there will be a message to double check your former input, touch 1 to confirm and 2 to make a reinput.

Now input the second equation and touch ENTER, the result will jump out in a second. Write down the answer qiuckly and then enjoy the baseball match!!
