(4) (Left Side) - (Right Side) result
"(Left Side) - (Right Side) result" shows the result when the right side of
the equation is subtracted from the left side, after assigning the obtained
value to the variable being solved for. The closer this result is to zero, the
higher the accuracy of the solution.
