Today, I realized that knowing math is no hard task. It's very simple. Now, the example above is just a silly example of what I'm saying but it's true: You add 2 to 2 and get 4, and you know math. If you know the following symbols, you know the basics.
÷ x - +
You just enhance your knowledge about math everyday in math class and one day, you're just going to stop learning. That last day of schooling. Then, it's finished. You'll go over the basics with your future son or daughter but that's it. So I believe you should learn the most you can about math while you're actually doing thinking-math and to enhance your ability to comprehend various concepts in your daily life.
