Halfway Between 0 and 642

When you ask "What number is halfway between 0 and 642?" 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=642.

Halfway Between Line

To find the number halfway between 0 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 642 into our formula, we get:

(0 + 642)/2 = 321

Thus, the number halfway between 0 and 642 is 321.

To check that our answer is correct, we subtract 0 from 321 and subtract 321 from 642 and compare the two numbers:

321 - 0 = 321
642 - 321 = 321

As you can see, the halfway number is 321 higher than 0 and 321 lower than 642. Therefore, our halfway between answer of 321 above is correct.
