Chosing learning topic

Im working on my hidden objects math game with Love-lei. We chose expressions with variables on both sides. When chosing it, I knew what I wanted to put in the game already. I decided with her because we could use it. Our game uses the equations to form coordinates on the logitude latitude plane. Also, we both found the topic easier than others in the subject. Thats it really for why we chose it. Bye!
