On this screen you can find information about the solution process. If you need to perform a different operation, press the button and select the appropriate operation.
How can I see the explanation of a single step?
You can obtain the explanation for any step by pressing on it. Please note that this doesn’t work for the very first expression, because that is the original problem (not a step).
Can some of the steps be eliminated, or do I have to see them all?
If you find the solution steps too detailed, press the settings button , to adjust the number of steps to a smaller number.
Can I see more steps (step details)?
If you want more details for the current solution process, press the settings button , to adjust the number of steps to a larger number.
What does solution ‘x ∈ R’ mean?
This means that any value of x will satisfy the equation. In other words, the solution does not depend on x.
What does solution ‘x ∈ ∅’ mean?
This means that the solution is an empty set – no value of x will satisfy the equation.
Why is Algebrator’s solution different from what I have in my book?
The most common reason is that Algebrator, by default, uses integers and fractions to represent the results. If you wish to have results in decimal form, press the settings button and change ‘Arithmetics’ from ‘Integer’ to ‘Real’.
