同学们，你们好．我是无理数．刚入初二第二学期我们就见面了，并且在今后的学习中我们还将经常在一起．不过，根据以往的经验，不少同学刚与我接触时，由于对我们无理数家族认识不深，常对我们产生一些似是而非的认识．为了帮助同学们更好地认识和了解我们，今天我归纳了以往? Hello, fellow students. I’m an irrational number. We just met in the second semester of the second year of junior high school and we will often stay together in the future. However, based on past experience, when many of my classmates have just come into contact with me, because of the lack of understanding of our irrational family, we often have some pessimistic understanding of us. In order to help students better understand and understand us, I have summarized the past today?
