Logic
mastery makes the hard, easier. Logic
mastery leads to better, stronger and richer comprehension. Logic

mastery gives a headstart. In sum, logic
mastery will develops critical thinking, improve reading and writing,
and give a firmer base for work and studies at many levels. Good luck.
After logic,

What may be learnt and when depends on how skills
and concepts are developed. Making the hard easier and clearer will allow
earlier & richer development of skills and concepts.

Counting or Tallying in Groups of Objects
Instead of counting via ones, we may group a set of elements into groups for tracking and tallying purposes. Now
5 groups + 4 groups = (5+4) groups
or more generally
A groups + B groups = (A+B) groups
The foregoing represents an initial distributive law for counting groups (or
units).
This initial or prototype distributive law for counting
groups with the aid of the following product rule implies the distributive law when the groups are equipollent
(that is, each group has the same number of elements, see below.)
The Commutative Law
A groups + B groups = B groups + A groups
follows from the identity
A groups + B groups = (A+B) groups
as A+B = B +A according to a previous lesson.
