Definition

What is it?

In logic, a 'move' is a single step or action taken to go from one idea or statement to another. It's like changing your position in a game based on a rule. Each move helps you get closer to a solution or conclusion.

Simple Example

Quick Example

Imagine you are playing Ludo. When you roll the dice and move your token from one square to another, that's one 'move'. In logic, it's similar: if you know 'all mangoes are fruits' and 'this is a mango', then saying 'this is a fruit' is a logical move.

Worked Example

Step-by-Step

Let's say you want to figure out what to wear based on the weather.

Step 1: You know it's raining outside. (This is your starting 'statement').
---Step 2: You remember the rule: 'If it's raining, I should carry an umbrella.' (This is your 'logical rule').
---Step 3: You apply the rule to your situation. Because it's raining, the rule tells you to carry an umbrella. (This is your 'move').
---Step 4: Your conclusion is: 'I should carry an umbrella.'

ANSWER: The move was applying the 'rainy day' rule to decide to carry an umbrella.

Why It Matters

Understanding 'moves' in logic helps you think clearly and solve problems step-by-step. This skill is crucial for careers in computer programming, where you tell computers exactly what 'moves' to make, or in law, where lawyers make logical 'moves' to argue their case.

Common Mistakes

MISTAKE: Making a jump to a conclusion without a proper rule or reason. | CORRECTION: Always ensure each 'move' is based on a clear, valid rule or a piece of known information.

MISTAKE: Skipping steps in your logical thinking. | CORRECTION: Break down your problem into smaller, individual 'moves'. Each step should be clear and justifiable.

MISTAKE: Using a rule that doesn't fit the situation. | CORRECTION: Double-check that the rule you are applying for your 'move' is actually relevant and correct for the information you have.

Practice Questions

Try It Yourself

QUESTION: If you know 'all dogs bark' and 'Buddy is a dog', what is the next logical move? | ANSWER: Buddy barks.

QUESTION: You have Rs. 50. A samosa costs Rs. 10. If you want to buy 3 samosas, what is the logical move to find out how much money you will spend? | ANSWER: Multiply Rs. 10 by 3, which equals Rs. 30.

QUESTION: Your mobile data pack has 1 GB left. You watch a video that uses 200 MB. Then you check WhatsApp, which uses 50 MB. What are the two logical moves to find out how much data is left? | ANSWER: Move 1: Subtract 200 MB from 1 GB (1000 MB - 200 MB = 800 MB). Move 2: Subtract 50 MB from the remaining 800 MB (800 MB - 50 MB = 750 MB). So, 750 MB data is left.

Real World Connection

In the Real World

When you use a navigation app like Google Maps to find the best route to school, the app makes many logical 'moves'. It processes traffic data, road closures, and your current location, then applies rules to suggest the fastest or shortest path, step-by-step, just like logical moves.
