The expression of 20-31 gives us the distance between the numbers 20 and 31 write a similar expression for the distance between - 5 and - 15 and simplify it.

After simplifying, our answer is 10

Step-by-step explanation:

20-31 gives the distance between 20 and 30

Now, for - 5 and - 15

The similar expression to write will be - 5 - (-15)

Simplifying this, we have;

That would be - 5+15 = 10
