Final answer:
Algorithms are problem-solving formulas that provide step-by-step instructions. They do not have to be written in computer code and are used to break down complex tasks. They are also commonly used in teaching and learning.
Step-by-step explanation:
An algorithm is a problem-solving formula that provides step-by-step instructions to achieve a desired outcome. They are not necessarily written in computer code, as they can be in natural language or represented using flowcharts and diagrams. Algorithms break complex tasks into manageable steps, making problem-solving more efficient and organized. They are also widely used in teaching and learning, serving as the basis for understanding problem-solving strategies in various fields.
