#### Answer:

The guess and check method is a form of a trial and error method.

pick a number for the equation plug it in and see how close the answer is. Adjust and guess again.

An example is artillery fire. The gunners pick a number that is thought to be close by a little big. The place of the hit is recorded.

Then the gunners pick a number that is thought to be a little small.

The place of the it is recorded. Now the real answer is located somewhere in the middle. From the distances ( or values) above and below the actual answer can be calculated. Another guess is made usually right on or very close.
