It’s an equation where you’re given the solution; now you just need to find out how you got there...
Expect to see and learn how to solve questions like this one:
Operator search puzzles are deceptively simple-looking, but they instill a deep familiarity with the behavior of operators over a given domain. They can lead to an understanding of how to invert an operation, how repeated operations stack, or what types of outputs to expect from a given operator. This knowledge can be extended far past simple arithmetic operators; even a new, completely made-up function can be described in terms of its identity, inverse, or its closure over a certain domain.
