Expert Answer
Errors can be positive or negative. For example, Negative error means your actual yield is higher than your theoretical yield. This happens mainly because of contamination or weighing errors.
For example, let's say you're trying to create water. If your beaker contains water already, then your actual yield may be more than the theoretical. Certain errors like the percent errors are always positive, since they are the absolute values,or the numbers are taken under the mod symbol.
