BIC, Bayesian Information Criterion; ΔBIC, BIC difference with respect to the null model (M0); LogBF, approximated bayes factor respect to the best model (M11) calculated through the relative likelihood [i.e., (ΔBIC/2)]. The higher the ΔBIC the better the model. Strategy, type of strategy (i.e., counting, retrieval, decomposition, and written calculation); Grade, 3rd and 5th grade; Complexity: single or double-digit subtrahend; Condition (absence or presence of borrowing procedure); Pres.form, vertical and horizontal presentation format.
