Halfway Between 0 and 20

When you ask "What number is halfway between 0 and 20?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=20.

Halfway Between Line

To find the number halfway between 0 and 20, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 20 into our formula, we get:

(0 + 20)/2 = 10

Thus, the number halfway between 0 and 20 is 10.

To check that our answer is correct, we subtract 0 from 10 and subtract 10 from 20 and compare the two numbers:

10 - 0 = 10
20 - 10 = 10

As you can see, the halfway number is 10 higher than 0 and 10 lower than 20. Therefore, our halfway between answer of 10 above is correct.
