Are there cases where the bar notation is useful other than confusing poor unsuspecting readers?

Oh. So the bar isn't actually a negative? Why would they decide to write it this way? o_O

It is off for the next value in the same problem too. It calculates $$ \log_{10}{0.004236} $$ as -3.6269 while with a calculator I get -2.373044. Even weirder is that it proceeds to add the two logarithms (which it calculated as -1.4643 and -3.6269) to get -3.0912. Then it proceeds to take the...

Today I came across a high school math book which has a particular problem in the logarithms chapter. It has $$ \log_{10}{0.2913} = -1.4643 $$ Trying to verify it with a calculator, I get -0.53566. There's a log table attached at the end which agrees with the calculation made in the book. To...
