Can someone help explain to me the step by step process of solving the following logs probs?

log2(6) - log2(15) - log2(20)

These logs have a base of two, and the answer for this problem is 3 but I don't understand how to get that answer. I do understand that logs in the form of a subtraction, i.e. : loga-logb= a/b but I'm unclear how to aproach the problem with three logs in the equation.
