You guys I had the most fun doing this project because I am a total math buff. Don't be afraid it's just numbers. I think I fell in love with numbers in the third grade or something when every Friday my math teacher used to give us a speed multiplication test. I would always study hard to finish first place. My mom would drill me at home and then I would practice on my own with flash cards. Eventually I would get faster and faster until I finished about 50 problems in 1-2 minutes. Of course I would finish first and get one hundred percent correct. I don't remember getting any type of reward, but the fact that I had recognition from both my peers and adults was enough for me.
Math is For Adults Too
Yes, once you reach adulthood, you don't need to stop liking math. Make it fun. Do something different that will benefit you and others. Make a game. What? Exercise your mind and prevent even Alzheimer's disease or dementia. Yeah, if you don't get your main nugget motivated you might end up a vegetable. Challenge yourself to difficult things, you might like it. I am a nerd and proud of it. I don't have big huge glasses or have pens stuck in my pockets. I'm just disguised differently with long hair and some makeup sometimes. I love computers and cooking. I'm not your average nerd. I'm a girl.
I am practicing my C# skills, so I learned to program this math game for everyone to enjoy. Hope you like it.
