Migração da revista Educação Matemática pesquisa para OPJ 3

Dear readers and authors of Educação Matemática Pesquiva,

We ended up migrating to OPJ 3. You may eventually encounter some problems in accessing the journal, in submitting and/or evaluating articles. These potential problems will soon be resolved.

Thanks for understanding
Saddo Ag Almouloud and Ana Lucia Manrique (Magazine Managers)
