Step-by-step explanation:
You may have visited certain cities in winter, or seen some movies showing very cold weather in other places. Do you know that the temperatures in very cold weathers are often below zero? For example, the winter temperature in Harbin, a city in northern China, may be 16 degrees Celsius below zero.
Mathematically, we express this situation of ‘below zero’ using negative numbers. A negative number is shown by placing the ‘–’ sign in front the number. Thus, the above temperature in Harbin would be –16 °C, which is read as ‘negative sixteen degrees Celsius.’
Can you think of other situations where you would use negative numbers?
