{"level":"Level 5","problem":"For each positive integer $n$, the set of integers $\\{0,1,\\ldots,n-1\\}$ is known as the $\\textit{residue system modulo}$ $n$. Within the residue system modulo $2^4$, let $A$ be the sum of all invertible integers modulo $2^4$ and let $B$ be the sum all of non-invertible integers modulo $2^4$. What is $A-B$?","type":"Number Theory"}
