The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so

It is often used in science to report the difference between experimental values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful to know if the error Therefore, always subtract the smaller value from the bigger. Reply ↓ Todd Helmenstine Post authorJanuary 28, 2016 at 2:15 pm Thanks for pointing that out. We can also use a theoretical value (when it is well known) instead of an exact value.

Thank you,,for signing up! Did you mean ? You can change this preference below. You measure the sides of the cube to find the volume and weigh it to find its mass.
