Dummy it down - Tradução em português

Olá pessoal! O que significa dummy it down nesse contexto? Qual a melhor tradução?

Plug in real numbers . In other words, “dummy it down” by using
convenient numbers in place of letters (variables) to make a problem
more concrete. This very powerful strategy can be used on multiplechoice
questions as well as the grid-in questions.

thanks in advance
