Definition
What is it?
6 - 1 means taking away 1 from the number 6. It is a simple subtraction problem where you find the difference between two numbers.
Simple Example
Quick Example
Imagine you have 6 ladoos on a plate. If your friend eats 1 ladoo, how many are left for you? You started with 6, and 1 was taken away, so 6 - 1 will tell you how many remain.
Worked Example
Step-by-Step
Let's find out what 6 - 1 is:
1. Start with the number 6. You can think of having 6 items, like 6 cricket balls.
---
2. The 'minus 1' part means you need to take away 1 item from your 6 cricket balls.
---
3. So, if you have 6 balls and you give 1 away, count how many are left.
---
4. You will be left with 5 cricket balls.
---
So, 6 - 1 = 5.
Why It Matters
Understanding simple subtraction like 6 - 1 is the basic building block for all higher maths, computing, and even AI. Computer programmers use subtraction to manage data, and AI systems use it for calculations. It's crucial for careers from data scientists to game developers.
Common Mistakes
MISTAKE: Adding the numbers instead of subtracting (e.g., thinking 6 - 1 = 7) | CORRECTION: Remember the minus sign '-' means 'take away' or 'find the difference', not 'add'.
MISTAKE: Counting backward from 1 instead of from 6 (e.g., thinking 6 - 1 = 0) | CORRECTION: Always start with the first number (6) and count backwards by the second number (1).
MISTAKE: Getting confused by the order (e.g., thinking 1 - 6 is the same as 6 - 1) | CORRECTION: Subtraction order matters! 6 - 1 is different from 1 - 6. Always subtract the second number from the first.

The Correct Answer Is:
B
Taking away 1 from 6 means 6 - 1. If you count backwards one step from 6, you land on 5. Options A, C, and D are incorrect because they represent addition, the original number, or the number being subtracted.
Real World Connection
In the Real World
Every day, we use subtraction. When you check your mobile data balance, and it shows 6 GB remaining, but you watch a video that uses 1 GB, your phone calculates 6 - 1 = 5 GB left. This simple math is happening in the background of apps like Paytm and during online shopping.
