Definition

What is it?

Both means that two or more things are true or present at the same time. It helps us talk about situations where two conditions must be met. Think of it as needing everything on a list to be true.

Simple Example

Quick Example

Imagine your teacher says, 'You can play football if you finish your homework AND clean your room.' You can only play if BOTH your homework is done AND your room is clean. If only one is done, you still can't play.

Worked Example

Step-by-Step

PROBLEM: Your school library has a rule: To borrow a science book, you must have a library card AND your previous book must be returned.

Step 1: Check if you have a library card. Let's say, YES, you have one.
---
Step 2: Check if your previous book is returned. Let's say, YES, it is returned.
---
Step 3: Apply the 'Both' rule. Is your library card present (YES) AND is your previous book returned (YES)?
---
Step 4: Since BOTH conditions are YES, you can borrow a science book.

ANSWER: Yes, you can borrow a science book.

Why It Matters

Understanding 'Both' is key in computer programming and artificial intelligence. It helps computers make decisions based on multiple conditions being true. Data scientists and software engineers use this logic to build smart systems, from search engines to self-driving cars.

Common Mistakes

MISTAKE: Thinking 'Both' means 'either one is enough' | CORRECTION: 'Both' means ALL conditions must be true. If even one condition is false, the 'Both' statement is false.

MISTAKE: Confusing 'Both' with 'Or' | CORRECTION: 'Both' requires every single condition to be met. 'Or' means only one of the conditions needs to be met.

MISTAKE: Not checking all conditions when using 'Both' | CORRECTION: Always check every single condition listed. If any condition fails, the 'Both' statement fails.

Practice Questions

Try It Yourself

QUESTION: Your mom says, 'I will buy you ice cream if you finish your dinner AND help me wash dishes.' You finished dinner but didn't help wash dishes. Will you get ice cream? | ANSWER: No

QUESTION: A mobile game requires you to have 100 coins AND 5 power-ups to unlock a new level. You have 120 coins and 4 power-ups. Can you unlock the new level? | ANSWER: No

QUESTION: To get a discount on a new cricket bat, the shop says you need to be a student, have a valid ID card, AND make a purchase over Rs. 1000. You are a student, have a valid ID, and bought a bat for Rs. 950. Do you get the discount? | ANSWER: No

MCQ

Quick Quiz

Which of these situations requires 'Both' conditions to be true?

You can go to the park if it's sunny OR you finish your homework.

You can eat pizza if you are hungry OR it's a weekend.

You can borrow a book if you have a library card AND you return the previous book.

You can watch TV if you finish your studies OR help your parents.

The Correct Answer Is:

Option C uses 'AND', which means both conditions (having a library card and returning the previous book) must be true. The other options use 'OR', where only one condition needs to be true.

Real World Connection

In the Real World

When you apply for an online service like a bank account or a new mobile connection, the system often checks if your Aadhar card is verified AND your PAN card details are entered correctly. Only if BOTH are true, your application moves forward. This 'Both' logic keeps our online transactions secure and correct.

What to Learn Next

Great job understanding 'Both'! Next, you should learn about 'What is Or?'. It's another important logical concept that helps computers make different kinds of decisions, and it's often used with 'Both' to create even smarter programs.
