To work out a trip planner on your computer, the most appropriate choice from the provided options is algorithm.

Explanation:

1. Algorithm: In the context of a trip planner, an algorithm refers to a set of steps or rules to be followed in calculations or other problem-solving operations. Algorithms are essential for computing the best routes, estimating travel times, and even managing costs associated with the trip.

2. Multiplication and Subtraction: While these are fundamental mathematical operations, they are not specifically tailored to planning trips. They can be involved in calculations within an algorithm, but alone, they do not effectively represent the process of creating a trip planner.

3. Code: This term refers to the actual programming used to implement algorithms. While coding is crucial for developing a trip planner, it does not describe the logical process behind the planning itself.

In summary, the best answer is algorithm, as it encapsulates the systematic approach to tackling the problem of trip planning.
