Many equations in the world simply cannot be solved without i.

Such an equation cannot be solved for one factor in terms of another.

The differential equation can be solved using a different approach.

These equations can be solved in a number of well-known ways.

Most of these rules are now known as the proper way into solving certain equations.

Li does not explain how to solve equations in general, but shows it with the example problems.

This equation may be solved by several methods, including the classical power series approach.

For each bit an equation is solved after 8 bits have been shifted in.

Now we can solve differential equations and send men to the moon.

And they are encouraged to think up different routes to solve equations.
