Logic
mastery makes the hard, easier. Logic
mastery leads to better, stronger and richer comprehension. Logic
mastery improves reading and writing. Logic
mastery ease learning difficulties. 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,
(a) continue reading Three
Skills for Algebra, chapters 8 to 14 and do so alongside site area on solving
liinear Equations ; or (b) see this calculus

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.

Talk the algebra talk
Arithmetic and algebraic expression, formulas and equalities,
being difficult to read aloud in ways that verbally describe order of
operations, will still is a source of silence. But the silence can be
ended, at least in part. F Online algebra chapters
8 to 14 show (i) how to describe numbers with words apart from
and besides symbols; and show (ii) how to use describe formula usage as direct
or indirect, and describe indirect use as a numerical or algebraic
solution. There-in a new base or extension of the use of words in algebra.
Your earlier difficulties in learning and teaching algebra come from the
lack of clear algebra talk (a clear words and terms) in describing
numbers and operations on equations and formulas. Introducing words and terms
(short descriptive phrases) to describe and identify skills and concepts
clearly codifies objectives in algebra, present but hidden by silence, but now
exposed by words easily understood and repeated.
Arithmetic and algebraic expression, formulas and equalities, being
difficult to read aloud in ways that verbally describe order of
operations, will still is a source of silence. That silence that may be
broken or lessened by numbering, naming or giving short descriptive phrases to
identify the expressions, formulas and equalities with written or spoken
words.
If you would like to know why slopes are studied in algebra, or if you
need a simple calculus preview or two, examine this geometric
preview and the more algebraic chapters
2 to 6 in Volume 3, Why Slopes and More
Mathematics. The previews may ease or avoid algebra difficulties in and
before calculus.
The algebraic preview includes sign and monoticity analysis of factored
polynomials, and location of maxima and minima. Monoticity analysis identifies
intervals where a calculation y = f(x) is increasing or decreasing.
This complex number starter lesson gives
a analytic geometry viewpoint - a coordinate-based alternative to
algebraic views met in pre-calculus learning and teaching. The
distributive law follows applied or mixed math-style from the assumption that
vector addition in the plane is independent of coordinate system. Despite
modern math curricula of the 1960's and their present-day echoes, math
education in trig to calculus, and in coordinate-free Euclidean Geometry, was
not pure.
