lowest one is 44 cm

The integer 0 represents ground level

Any positive number is some distance above ground. Example: the number 5 means you are 5 units above ground level.

Any negative number is where you're underground as the picture shows.

The value 0 is right in the middle. It divides or forms a wall between the positive and negative numbers. So naturally 0 is a good place to have the ground. You can think of it as floors in an elevator if it helps.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
