引入负数后,将会带来一系列的变化,下面我们就跟随刘老师去看一看吧.王老师说:“这些天我们接触了一个新伙伴——负数,自从有了它,数的家族发生了不少变化.谁能说说吗?”小明说:“引入负数以后,0就有了更丰富的内涵,它不仅是表示没有了.比如某天24时的温度是0℃,不是说没有温度,而是表示一个确定的温度;又如某地的海拔高度是0m,不是说该地没有高度,而是表示该地与海平面的高度一样.”
After the introduction of negative numbers, will bring a series of changes, here we follow Liu to see it.Wang said: “These days we have come into contact with a new partner - a negative number, since it has, a few Family has made a lot of changes. ”Who can say?“ Xiao Ming said: ”After the introduction of negative numbers, 0 has a richer connotation, it is not only said no. For example, 24 o’clock on the day the temperature is 0 ℃ , Not to say that there is no temperature, but rather to indicate a certain temperature. For another example, the altitude above sea level is 0m, not to say that there is no altitude, but to indicate that the sea level is the same as the sea level.
