VAMOS EXERCITAR O CÁLCULO MENTAL.
Se
observares com atenção, vais conseguir resolver estas 40 operações sem
usar os algoritmos.

É melhor
escreveres primeiro com lápis num caderno e verificares com cuidado, uma por
uma.
Depois
copias com muita atenção para os comentários do blogue.
Às 15 horas, publicarei aqui as soluções e deves corrigir, com
muita atenção, o que escreveste nos dois sítios - no caderno e no blogue.
