Read  logic chapters 1 to 5  in online volume Three Skills for Algebra  
Then seek 4 skills for algebra in it.

Learn to read notes and textbooks like a lawyer, so that no nuance, no subtlety and no clause escapes your attention

 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

Do not leave here without it -  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 linear2007 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.


George Orwell:   Is it nonsense for arts and disciplines based on and respected for carefully  mastery of rules and methods, alone and combined, to face education reforms based on the supposition that mastery of rules and methods is not a sign of intelligence.  Would you like to rewrite 1984 to include that angle?


Try the Twiddla Whiteboard. In principle, it  allows to people to draw and chat together online on a copy of this webpage or a clean sheet. The chat may be via text or audio.  Visit twiddla.com to set up whiteboards to work with the webpage of your choice.

Precalculus sites mathsisfun & purplemath are visually more appealling than this one.  Do not go. 

For online automated help in senior high school maths & calculus, visit  quickmath.com  For Automatic Calculus and Algebra Help with derivatives, integrals, graphs, linear equations, matrix algebra, visit calc101.com  With  overlap, each site quickmath & calc101offers a different range of services, some free, some not, all based on webmathematica. Good luck.

 

Skill and Knowledge Checklist
with goals, values and standards to adopt
Identify what to learn to be better than you expect

From algebra to calculus, site appetizers and lessons introducing the shorthand roles of letters and symbols provide clearer and fuller explanations.  In or for algebra and beyond, mastery of fractions, roots and powers, what they are, along with an exact, efficient written command of operations on them with proper notation is a must. Add all the foregoing to your goals. 

  1. Can you do Arithmetic with whole numbers and fractions efficiently without a calculator? Lack of emphasis on this in  high school courses invites in mathematics difficulties beyond arithmetic. . See these arithmetic problems with hints of algebra. If they are too hard, get help - for instance, you could leave this site to explore aaamath. and Purplemath carefully and then return.   

    Fraction sense (what they are and an efficient command of their addition, multiplication and division)  is a must for mathematics even if your high school do not emphasize it in what is therefore substandard instruction.  Site pages on fractions need to be rewritten to make them clearer.  None the less, follow what you can in them and be sure to master fractions here or elsewhere by yourself or with help.

  2. Have you mastered Euclidean logic? This subject disappeared from mathematics courses due to the vanishing of Euclidean geometry with its theorems and proofs. But it can be mastered apart from mathematics. See Volumes 1A (all) or chapters 1 to 6 in Volume 2 to learn how. Mastery of Euclidean logic leads to precision reading and writing - two musts for school and work - and shows how and when to apply implication rules, one at a time and one after another, to arrive at conclusions directly and indirectly. The math-free treatment here would be a plus for course design in secondary school.

  3. Do you know how to describe numbers and quantities precisely apart from arithmetic and algebra as this topic is new to your teachers. The skill of describing and talking about numbers is an missing in the description or exposition of mathematics. The essay what is a variable and chapters 8 to 12 in Volume 2, Three Skills for Algebra, offer a remedy and then introduce or review the shorthand role of letters in formulas and equations. The rhetorical introduction here to the description of numbers and quantities apart from and then besides the use of letters would be a plus for course design in secondary school.

  4. Do you know how to use formulas directly and indirectly in algebra? Chapter 14 in Volume 2, gives arithmetic and algebraic solutions for problems involving compound growth problems, and in doing so develops another key skill in algebra. The skill is a must for all students high school and college. Chapter 15 goes further and says how to solve linear equations in one and more unknowns. The more part should be rewritten.

  5. Can you visualize complex numbers and connect them to trig and the law of signs? Read this complex no intro and the associated site area to build upon an old way to visualize the square root of -1. The introduction here with rectangular and polar coordinates is useful for engineering and physics, if not mathematics. Students may read this introduction and its variations before or besides trig. The introduction here would be a plus for trig in secondary school. See Site Reviews

  6. Do you know to make Calculus simpler for your self or others? Site material gives a different starting point for calculus, one that puts the easiest material first. The path gradually develop algebraic skills instead of demanding them suddenly. See this Visual  Preview and/or read chapters 2 to 18 in Volume 3 besides other notes or texts in calculus. Calculus Teachers: Make matters easier for your students by following the path and introducing in the first instance, only those limits strictly needed for continuity, derivatives and integrals. Discussion of infinite limits, one-sided limits, and limit evaluation tricks should be a late sideshow in one semester courses. The decimal viewpoint of limits is sufficient for all students outside of advanced mathematical courses and could be a starting point for the decimal free views of limits, continuity and compactness. See Chapter 14 and (?) the appendices in Volume 3. The path shown here would ease or avoid troubles in most calculus courses. See Site Reviews
