For example, one important feature of a set with a particular operation may be whether or not certain kinds of equations can always be systematically solved within that set. For example, you learned in previous algebra classes that linear equations can always be solved if we are working with real numbers. Let's look again at how you would normally solve a linear equation in the real numbers:
