- 1`#We are going to "transform"
- 1`#the algebraic expression:
- 1`#"$x+2(x-3)"$.
- 1`#to its simplest form.
- 2`#We open the &Transformations& window and write the problem.
- 3`"After formulating the problem we press &ENTER&."
- 5`After pressing &ENTER& the window splits into two parts.
- 5``#The upper (blue) part contains "the problem".
- 5``#In the lower (white) part of the window
- 5`#we write "the transformed expression".
- 6`#As the first step of transformations we can type:
- 6`#"$x+2x-6"$.
- 6`#The marked text disappears when we begin typing.
- ;6`#The expression we are to transform is
- ;6`#in the upper (blue) part of the window.
- 7`#We have made some transformations so we "press &ENTER&".
- 8`Our transformation was "checked" and is "noted" as &Step 1&.
- 8`#A new blue tab appears.
- 9`#As the next step of our transformations we type:
- 9`#"$3x-6"$.
- 9`#The marked text disappears when we begin typing.
- 10`We "press &ENTER&" again.
- 11`#This is the simplest form of the expression.
- ;11`#We press the &Answer& button.
- ;11`#The mouse is pointing at it.
- 11``#To inform the program that this is &the final result&
- 11`#"we press &ENTER&"
- 11`#&without making any changes& in the expression.
- 12`We can look through all the steps.
-
- 100`#The main idea of working with 2xy is very simple.
- 100``#To transform expressions you open the &Transformations& window.
- 100``#"You write your problem in the window, and press &ENTER&."
- 100``#"You make some transformations, and press &ENTER&."
- 100``#"You make some transformations, and press &ENTER&."
- 100``#"You continue in this way ... until"
- ;100``#"you obtain the final result; then you press the &Answer& button"`
- 100``#"you obtain the final result; then you press &ENTER&"
- 100`#without making any changes in the expression.
-
- 101`#We learn how to use 2xy.
- 101``#"The presentation proceeds automatically."
- 101``#To move yellow panels use the mouse.
- 101`#Press ENTER on the KEYBOARD to continue.
-
- 102`#In a moment the &Examples& window will appear.
- 102`You can watch the same presentation again, or
- 102`#load the next example, or
- 102`#close the window and solve your own problem.
