Logic chapters 1 to 5 re- appear not in sequence, as is or longer, in Volume 1A, Pattern Based Reason, Bon Appetite.
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.

Calculation of Velocity
Note that speed is an everyday term. It is never negative. In the above graph, the speed is given by the magnitude (absolute value) of the slope m. In contrast, velocity is a technical term. In can be positive, zero or negative. In a distance d versus time t graph, the velocity v is given by the slope m, and can be positive, zero or negative.
A graph of Barbara's position versus time follows. Find her velocity for each portion of her journey }
if the coordinates of the ends of each line segment in the above graph are as
follows.
|
P1 = (0min,80 km) |
P2 = (30min,40 km) |
| P3 = (60min,120 km) | P4 = (90min,120 km) |
| P5 = (150min,90 km) | P6 = (210min,0 km) |
Solution. The rise over run ratio gives the following slope mj on the j-th interval for 1 £ j £ 5, that is for j=1,2,3,4 or 5. The calculations ad nauseum follow.
