back to basics

Back to fundamental principles, as in The plans are much too elaborate; to stay in our budget we have to get back to basics. At first this term was used mainly for schooling that stresses proficiency in reading, writing, and mathematics (also see three R's), but it quickly was transferred to other areas. [1970s]
