LOGICAL THINKING AND DECISION MAKING

Logical thinking is when you make decisions based on facts and rules, not feelings
or guesses. While solving a maths problem or following a set of rules in a game,

logical thinking is always used.

Example:

 Not logical (feelings/guess): "I think it will rain because I feel sad today."

 Logical (facts/rules): "The weather app says 80% rain and dark clouds are in the
sky. So, I will take an umbrella.”

One of the most important elements in algorithmic thinking is the decision.
Sometimes, you need to choose between options. This is called decision making.

For example, deciding what to wear.

 If it is raining → Wear a raincoat.

 If it is sunny → Wear light clothes.

These are called conditions (if–then statements). Conditions are used to make
decisions based on specific situations. They help in deciding the action to take

depending on whether the condition is true or false.

Algorithm:

Step 1 Start

Step 2 Check if it is raining

Step 3 If YES → Take an umbrella
Step 4 If NO → Do not take an umbrella
