Halfway Between 0 and 80

When you ask "What number is halfway between 0 and 80?" 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=80.

Halfway Between Line

To find the number halfway between 0 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 80 into our formula, we get:

(0 + 80)/2 = 40

Thus, the number halfway between 0 and 80 is 40.

To check that our answer is correct, we subtract 0 from 40 and subtract 40 from 80 and compare the two numbers:

40 - 0 = 40
80 - 40 = 40

As you can see, the halfway number is 40 higher than 0 and 40 lower than 80. Therefore, our halfway between answer of 40 above is correct.
