THIRD PART OF BRAILLER ÁBACO
To write quantities put the abacus on the table, so that the wide rectangle is down, hold it with both hands and verify that the abacus is zero or that next to the horizontal bar there is no account.
When you lower the accounts that are on top to the horizontal bar or Rule, use the index finger of the left or right hand as required, in the case of the bottom beads, raise them with the thumb and erase them with the index finger. This does not mean that if the child uses other fingers, the I'm doing inadequately.
Now I located the first axis that is on the right in the first class that corresponds to the units following the illustrations below and write the following numbers:

Buen trabajo amigo. Cuidado con las etiquetas, para este caso yo usaría primero science, te da mucho mas alcance, necesitas votos. Y de segundo pondría society, y luego las otras. La etiqueta steemit solo se debe usar para cosas de la plataforma, como la criptomoneda, sugerencias a la red y esas cosas. Próximamente te estaré ayudando mas, el tiempo se me queda corto para apoyar a tanta gente, pero lo estoy logrando. Cuenta con ello amigo. Excelente contenido by the way. Inclusive en este caso creo que hubiera usado la etiqueta curie, ya que a @curie le fascinan estas cosas hermano.
Muchas gracias Reinaldo.
