In my second entry I am talking about tables. Tables are mostly used to compare or see the number that is part of a graph. For example: x y
10 30
20 60
30 90
40 120 and so on.
You could compare the numbers in x with the numbers in y. That is why tables are very useful. They are the repeated solving of an equation. Tables can have millions of numbers from any side negative or positive. They can compare any variables that include numbers. For example with money or amount of animals, computers,rivers,etc.
