Logic Mastery
 Amazing, Amusing, Amorous,  Delicious, Delightful, Edifying, Strengthening Elixir. 
It eases work & learning difficulties Makes the hard easier. Opens eyes. Leads to greater precision.
in reading and
writing

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 starter lesson and Volume 3, Why Slopes  & More Math, chapters 2 to 6;

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.

Appendix B
How to Learn

Here are five more suggestions for learning well.

A  Look for New Ideas

First, learning will be the most rapid when you look for ideas new to you. They make your studying a subject for the first or last time, worthwhile. Meeting familiar ideas may refresh your memory but you only learn from new ideas. The familiar ones will take care of themselves. When you can find no more ideas new to you, your study or review of a subject is done - or you are tired and you need a rest before starting again.

B  Look for Names

Second, look for the names of ideas, places and people. Coin or invent names if need be. An idea, object or person once named or identified is yours to speak or write about. Names may banish the vague or unclear use of the words it and they from your speech and writings.1

1In old and possibly some present-day religions, people thought that another's knowledge of their names made them vulnerable to spells and curses. Today knowledge of your name, address or various identification numbers make you more vulnerable to a loss of privacy, junk mail, and legal proceedings - a kind of spell different from that previously envisioned or anticipated yesterday.

C  Proceed (Go) Step by Step

Third, find a step by step explanation or description of the skills you need. Then begin your study of a subject at a step where everything is understood. Starting elsewhere leads to confusion. It may cause you to turn away from the subject. In particular, if you try to master a subject too quickly, you will find some skills are too hard. Then you will need to start again with the simpler ones before them. You may further need to ask someone about which skills you will need to know to master the ones hard for you. Lessons taught by others, or self-taught, must build new skills on those previously mastered.

D  Be Persistent
(Be Stubborn)

Fourth, understanding whatever you have to do or read takes time. If you have ever done a crossword or jigsaw puzzle, then you know you can work on one part of the puzzle and then another. Each part you do, manage to solve or understand, may help with the rest of the puzzle. The same is true of a book or class notes. Read them in order if you can. But do not be afraid to look ahead, or behind, for clues to what the current passage or word means. So read with patience. Be prepared to puzzle or think. Further, do not hesitate to get a second opinion or view from another person or book. The words of others may provide a path to follow but the understanding of any subject is an individual effort. No one else can do this for you. So be persistent and look for the ideas new to you.

E  Ask Why

Fifth, ask your teachers why each course or lesson is given, or what they hope to show you. Reasons for learning this or that can be requested.

Sometimes we teachers cannot give a full answer - our employees (School boards) may have told us to teach you a topic based on great or little wisdom. In education, too many cooks spoil the broth.
