Put this on your index cards for studying.  Or put it in Quizlet.  Or put it in your study notebook.

That’s it.  Make sure you practice these and get really strong at them and you may not need to think of this adage eventually.  Yet this is an excellent adage to keep in mind for these problem types as you work through logarithms in your class/es.
