What number is halfway between -3 and 4?

The decimal 0.5 or (+ 1/2)

To find a halfway point (which is also the average), add the numbers together and divide by 2.

-3 + 4 = 1 and 1/2 = 0.5, which is 3.5 more than -3 and 3.5 less than 4
To figure this out, add the two numbers, then divide the result by 2.

= 0.5
