Error calculation in TH1


I’m a new root user, and I wanted to check how root calculates and propagates errors for histogram bins. I would guess it is binomial errors, but where would I look for that information? If I scale a histogram by -1 to subtract it from another, does it use standard error propagation to get the new histogram’s errors? Thanks in advance for taking your time to look at this question.
