加法的自述自盘古开天地后 ,人们在生产生活中孕育了我———加法 .我是人类智慧的结晶 ,并且随着人类不断完善自我 !现在的人一听说加法 ,就知道我这个加法是数学运算中最低的一级运算 ,简单得不可再简单 ,简单得不足挂齿 .可就一个加号“ +”就花了人类几千年才演变出来 .现 After the addition of the self-declaration of the ancient world, people in the production and life gave birth to me --- Addition. I am the crystallization of human wisdom, and as humans continue to improve themselves! Now that people have heard of the addition, I know that this addition It is the lowest level of arithmetic in mathematics operations. It’s simple and simple. It’s too simple to hang the teeth. It took a few thousand years for a plus sign “+” to evolve.
