When the final (correct) solution is reached, an appropriate message will appear
and no more red expressions will be generated.

Do not confuse the

button, with the

button. The former is

used as described above, while the latter is used to explicitly check the validity
of a solution to an equation or inequality.

Setting solution parameters
Solution settings
Solution settings tell the software how to solve certain kinds of problems.
Quadratic equations can be solved by using one of the following three methods:
Factoring
Completing the square
Quadratic formula

Systems of equations have three different methods available:
Elimination
Substitution
Cramer’s rule
If your problem does not explicitly state which method to employ, it is better to
let the software decide which is the most efficient method, by selecting the
fourth item in the list: Smart choice.

You can make the software choose between real and integer arithmetic (i.e. in
an equation, x=1/2 would indicate "integer" while x=0.5 would indicate "real"
arithmetic).
Sometimes it is hard to decide which setting will work better. Here are some
general recommendations:
Check your book and follow its form.
If an equation or expression already contains decimal numbers (i.e. 1.2x
+3.5=3.1), use "real" format; otherwise use "integer" setting. Note that if
