Every day, you face problems like deciding what to eat or organising a school event. Some problems are
easy to solve, while others are more difficult and need careful thinking and planning. In this chapter,
we will learn how to understand different types of problems, create step-by-step instructions called
algorithms, and use pseudocode to plan solutions.

INTRODUCTION TO PROBLEM-SOLVING

Problem-solving is a core skill that plays a major role in our personal, academic, and professional lives.
It refers to the process of identifying a challenge, analysing it, and developing effective strategies to
overcome it. Problem-solving improves decision-making, creativity, and confidence. From resolving
simple daily inconveniences to tackling large-scale challenges, problem-solving enhances your
decision-making, creativity, and confidence.

Every day, we solve problems—big or small. Whether you're figuring out how to fix a broken remote,
choosing the best way to organise your time, or resolving a disagreement with a friend, you're using
problem-solving skills. These skills not only make tasks easier but also boost your ability to think
critically and act responsibly.
