Halfway Between 0 and 644

When you ask "What number is halfway between 0 and 644?" 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=644.

Halfway Between Line

To find the number halfway between 0 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 644 into our formula, we get:

(0 + 644)/2 = 322

Thus, the number halfway between 0 and 644 is 322.

To check that our answer is correct, we subtract 0 from 322 and subtract 322 from 644 and compare the two numbers:

322 - 0 = 322
644 - 322 = 322

As you can see, the halfway number is 322 higher than 0 and 322 lower than 644. Therefore, our halfway between answer of 322 above is correct.
