1. A method or strategy that uses estimated values or rough calculations rather than exact precision; a pragmatic way of dealing with a problem that doesn't require absolute accuracy
Given the time constraints, we decided to take an approximate approach to solving the mathematical problem.
Considerando as limitações de tempo, decidimos adotar uma abordagem aproximada para resolver o problema matemático.
2. In academic or professional contexts, a preliminary or tentative method used to explore a subject before developing more detailed solutions
The engineer used an approximate approach to model the structure before conducting precise simulations.
O engenheiro utilizou uma abordagem aproximada para modelar a estrutura antes de conduzir simulações precisas.
