English term or phrase:guess-check-and-improve
You will learn a method called backtracking to solve equations. For example, consider the equation 4 ? n 1 5 5 t. To find an output (t) with this equation, start with an input (n), multiply it by 4, and add 5. The
following flowchart shows these steps.
Here’s the flowchart for an input of 3:
If you were given an output of 21, you could use the flowchart to work
backward and determine that the input was 4.
You’ll discover that some equations cannot be solved using backtracking. So, you’ll explore another method, guess-check-and-improve.
