Halfway Between 0 and 840

When you ask "What number is halfway between 0 and 840?" 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=840.

Halfway Between Line

To find the number halfway between 0 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 840 into our formula, we get:

(0 + 840)/2 = 420

Thus, the number halfway between 0 and 840 is 420.

To check that our answer is correct, we subtract 0 from 420 and subtract 420 from 840 and compare the two numbers:

420 - 0 = 420
840 - 420 = 420

As you can see, the halfway number is 420 higher than 0 and 420 lower than 840. Therefore, our halfway between answer of 420 above is correct.
