In week one or two of intro to CS at a community college level, students may not have been introduced to the concept of arrays, nested loops, unpack templates, map, and so on. However, anyone with grade-school math in their past understands remainders with integer division (ie, the modulus operator). What's amazing is that such a simple thing, taught in 4th grade, is useful to low-level-language programmers even today when using arithmetic to simulate multi-dimensional structures in flat memory.
