The example is attempting to avoid fractions for simpletons. Replace the word ‘khet’ with ‘unit’ to simplify. 1/9th of 9 is 1. Now take away 1 from 9. Remainder is 8. Multiply 8 with 8 yields 64. 8 is not a constant for other example but for this the example to obtain a round number result.

The mathematical statement is “square of 8/9th of the length of the diameter is the area of the round object”

8/9 = 0.8888888…9

]]>Counter-clockwise from the positive x and y

You go around, hit the II and then III

Bottom left, negative, remember that please

Now if you’ve got a single point on the x-y grid

There’s a single pair of values telling you where it is

The x coordinate goes side to side

The y follows the comma to define the point’s height

A straight line between two points is a relation

You can represent it with a linear equation

y = m times x + b
