- 1`#We are going to solve the "equation":
- 1`#@x-1+3x=7@.
- 2`#We open the &Equations& 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 equation".
- 6`#Now we want to write the first step of our calculations:
- 6`#"$-1+4x=7"$.
- 6`#The program copies our equation to the working part of the window.
- 6`#We can "edit" the expression to obtain the form we want.
- 7`We have made some transformations so we "press &ENTER&."
- 8`Our solution was "checked" and is "noted" as &Step 1&.
- 8`#A new blue tab appeared.
- 9`#The next step is:
- 9`#"$4x=8"$.
- 9`#As usual the program copies the last form of our equation.
- 9`#And we can "edit" it.
- 12`#We have made some transformations so we "press &ENTER&" again.
- 14`Our solution was "checked" and is "noted" as &Step 2&.
- 14`A new blue tab appeared.
- 16`For the next step we want to write:
- 16`#"$x=2"$.
- 16`#As usual the program copies the equation, we can edit it
- 16`#but it is easier to type &x=2&.
- 18`#This is the final result.
- 18``#To inform the program about it
- 18`#"we press &ENTER&"
- 18`#&without making any changes& in the expression.
- ;18`#"We press the &Answer& button."
- 20`#We can look through all the steps.
- 21`#"We press &ENTER& again."
-
- 100`#The main idea of working with 2xy is very simple.
- 100``#To solve equations you open the &Equations& 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 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.
