Definition
What is it?
6 x 7 asks you to find the total when you have 6 groups of 7 items each, or 7 groups of 6 items each. It is a basic multiplication problem, which is a shortcut for repeated addition.
Simple Example
Quick Example
Imagine you have 6 friends, and each friend brings 7 ladoos to a party. To find out the total number of ladoos, you would multiply 6 by 7. This tells you how many ladoos there are in all.
Worked Example
Step-by-Step
Let's find the answer to 6 x 7 using repeated addition.
Step 1: Understand that 6 x 7 means adding the number 7, six times.
---
Step 2: Start adding: 7 + 7 = 14.
---
Step 3: Continue adding: 14 + 7 = 21.
---
Step 4: Add again: 21 + 7 = 28.
---
Step 5: Keep going: 28 + 7 = 35.
---
Step 6: One more time: 35 + 7 = 42.
---
Answer: So, 6 x 7 = 42.
Why It Matters
Understanding multiplication is key for many things, from managing pocket money to advanced computing. Engineers use it to design buildings, and AI algorithms use it for complex calculations like facial recognition. It's a fundamental skill for almost any STEM career.
Common Mistakes
MISTAKE: Confusing multiplication with addition, e.g., thinking 6 x 7 is 6 + 7 = 13. | CORRECTION: Remember multiplication is repeated addition. 6 x 7 means adding 7 six times, not just once.
MISTAKE: Getting confused if the numbers are swapped, e.g., thinking 6 x 7 is different from 7 x 6. | CORRECTION: Multiplication is commutative, meaning the order of numbers doesn't change the product. 6 x 7 is the same as 7 x 6.
MISTAKE: Not knowing your multiplication tables by heart and trying to count on fingers every time. | CORRECTION: Practice your multiplication tables regularly. Knowing them makes calculations much faster and easier.

7 + 7 + 7 + 7 + 7 + 7
6 + 6 + 6 + 6 + 6 + 6
6 - 7
The Correct Answer Is:
B
Option B correctly shows 7 added 6 times, which is the definition of 6 x 7. Options A, C, and D are incorrect mathematical operations or repeated additions.
Real World Connection
In the Real World
When a delivery app like Swiggy or Zomato calculates the total cost for 6 identical food items, each priced at 70 rupees, it uses multiplication (6 x 70). This helps them quickly tell you the bill and process payments efficiently.
