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,
(a) continue reading Three

Slopes & More Math, chapters 2 to 6. In Volume 2, Three
Skills for Algebra, a 4th skill for algebra appears in Chapter 14. It
provides a unifying theme for high school mathematics - equations and formulas
may be used forwards and backwards, directly and indirectly, numerically in arithmetic
solutions & with literals in algebraic solutions.

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.

Chapter 4
Complex Numbers and Why Slopes
Reason itself appears in mathematics whenever we draw a conclusion from a
calculation, a diagram or from some implications rules employed in mathematical
definitions and assertions. The physicist Richard Feynman (1918-1988)
gave three public lectures at McGill University in 1979 (Printed version says
1976 in error). His work on physics has been followed by many scientists and
students[1].
[1] Apart from his more serious works, he
is the author of two light books, Surely You are Joking, Mr. Feynman!
Adventures of a Curious Character, 1985 and What Do You Care About What
Other People Think? Further Adventures of A Curious Character, 1988, both
distributed by Norton, New York.
In the lectures, most likely tongue-in-cheek, he suggested that physics was
based on two easily described operations, namely the addition and multiplication
of arrows in the plane. His description of arrow addition and multiplication for
a general, non-mathematical audience was a model for the informal, very
visual, yet also adequate, presentation of mathematical ideas. He gave it under
the guise of describing physics. And he avoided panic among the mathematically
shy by not saying that the arrows, with their addition and multiplication,
represent what pure and applied mathematicians (since Gauss) regard as the
complex numbers.
Two Topics, Easily Described
Talking about arrows, vectors and slopes are further parts of mathematics
besides rule-based reason and the algebraic way of writing and thinking. The
on-paper presentation of these glimpses is somewhat technical. They are much
easier to understand from a live presentation[2].
[2] What is not immediately understood below could be
left for as subject further inquiry – questions for someone more familiar
with late high school or early college math.

-Inductive
principles for course design & delivery require a clear
description of where and how skills and concepts may rest on earlier ones, so
that difficulties may be explained and remedied by looking for what was
missed or forgotten in earlier studies.
Mathematics is a demanding subject. All errors in notation
and comprehension need to be identified and corrected. In
reading, spelling and writing, students have to learn all the letters in the
alphabet, not just some. and memorize spelling. Anything less implies
difficulty.
Likewise in mathematics, students have to master key skills
and concepts, one at a time and one after another. Anything less implies
difficulty.
Modern mathematics curricula introduced an inconsistency
into course design and delivery. They did not sanction the use of decimals nor
the use of diagrams in skill and concept development but decimal arithmetic
and diagrams are needed for student comprehension and for an operational
mastery of quantitative skills. That implies the need for an mixed-math
curricula based on a systematic development of operational skills, sufficient
for applications and sufficient to provide a base & context
for the very optional study of pure mathematis.
