Definition

What is it?

The word 'Then' in logic means 'after that' or 'as a result'. It shows what happens next or what is true because something else happened or was true before. It connects an action or condition to its outcome.

Simple Example

Quick Example

If you study hard for your exams, then you will get good marks. Here, studying hard is the first part, and getting good marks is the 'then' part, the result.

Worked Example

Step-by-Step

Let's say your mobile data plan has a limit.

STEP 1: You have a 1 GB daily mobile data limit.
---
STEP 2: You watch many videos and use up all 1 GB of data before evening.
---
STEP 3: IF you use up all 1 GB data, THEN your internet speed becomes very slow.
---
STEP 4: So, your internet speed will become very slow. This is the consequence.

Why It Matters

Understanding 'then' helps you predict outcomes and make better decisions in life. It's crucial in computer programming to tell computers what to do next, in science to understand cause and effect, and in everyday problem-solving. Engineers and doctors use this logic constantly.

Common Mistakes

MISTAKE: Thinking 'then' always means 'at that exact moment'. | CORRECTION: 'Then' means 'as a result' or 'consequently', which might happen immediately or a bit later.

MISTAKE: Confusing 'then' (sequence/consequence) with 'than' (comparison). | CORRECTION: 'Then' is for order or result (e.g., 'first this, then that'), while 'than' is for comparing (e.g., 'taller than me').

MISTAKE: Assuming the 'then' part will happen even if the 'if' part doesn't. | CORRECTION: The 'then' part (the consequence) only happens IF the 'if' part (the condition) is met.

Practice Questions

Try It Yourself

QUESTION: Complete the sentence: If it rains heavily, then the cricket match will be _______. | ANSWER: cancelled (or postponed)

QUESTION: What is the 'then' part in this sentence: 'If you save money from your pocket money, then you can buy that new video game.' | ANSWER: you can buy that new video game

QUESTION: Your mom says, 'If you finish your homework by 7 PM, then we can watch a movie together.' You finish your homework at 7:30 PM. Will you watch the movie? Explain using 'then'. | ANSWER: No, because the condition (finishing homework by 7 PM) was not met. So, the 'then' part (watching a movie) will not happen.

MCQ

Quick Quiz

Which sentence correctly uses 'then' to show a consequence?

My brother is taller then me.

First I ate dinner, then I watched TV.

She is smarter then him.

I want to go to the park, then I will play.

The Correct Answer Is:

Option B correctly uses 'then' to show a sequence of events. Options A and C incorrectly use 'then' instead of 'than' for comparison. Option D shows a sequence, but 'then' here implies 'after that' rather than a direct consequence, making B a clearer example of logical consequence.

Real World Connection

In the Real World

When you use a food delivery app like Zomato or Swiggy, the app uses 'if-then' logic. For example, IF your payment is successful, THEN your order is placed. IF the delivery person reaches your building, THEN you receive a notification. This logic helps automate many services we use daily.

Key Vocabulary

Key Terms

CONSEQUENCE: a result or effect of an action or condition | LOGIC: reasoning conducted or assessed according to strict principles of validity | CONDITION: a state that must exist for something else to happen | OUTCOME: the way a thing turns out; a result.
