Halfway Between 0 and 30

When you ask "What number is halfway between 0 and 30?" 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=30.

Halfway Between Line

To find the number halfway between 0 and 30, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 30 into our formula, we get:

(0 + 30)/2 = 15

Thus, the number halfway between 0 and 30 is 15.

To check that our answer is correct, we subtract 0 from 15 and subtract 15 from 30 and compare the two numbers:

15 - 0 = 15
30 - 15 = 15

As you can see, the halfway number is 15 higher than 0 and 15 lower than 30. Therefore, our halfway between answer of 15 above is correct.
