Explain what absolute value tells about - 18 degrees Celsius.

| - 18 | = 18

Step-by-step explanation:

The value which is described as the distance of a number on the number line from the zero value (0) despite of which direction it is going is known as the absolute value.

Therefore, the absolute value of - 18 will be positive 18.
